The only time we use the int_combiner_irq[] and ext_combiner_irq[]
arrays in the Exynos4210Irq struct is during realize of the SoC -- we
initialize them with the input IRQs of the combiner devices, and then
connect those to outputs of other devices in
exynos4210_init_board_irqs(). Now that the combiner objects are
easily accessible as s->int_combiner and s->ext_combiner we can make
the connections directly from one device to the other without going
via these arrays.
Since these are the only two remaining elements of Exynos4210Irq,
we can remove that struct entirely.

At this point, the function exynos4210_init_board_irqs() splits input
IRQ lines to connect them to the input combiner, output combiner and
external GIC. The function exynos4210_combiner_get_gpioin() splits
some of the combiner input lines further to connect them to multiple
different inputs on the combiner.
Because (unlike qemu_irq_split()) the TYPE_SPLIT_IRQ device has a
configurable number of outputs, we can do all this in one place, by
making exynos4210_init_board_irqs() add extra outputs to the splitter
device when it must be connected to more than one input on each
combiner.
We do this with a new data structure, the combinermap, which is an
array each of whose elements is a list of the interrupt IDs on the
combiner which must be tied together. As we loop through each
interrupt ID, if we find that it is the first one in one of these
lists, we configure the splitter device with eonugh extra outputs and
wire them up to the other interrupt IDs in the list.
Conveniently, for all the cases where this is necessary, the
lowest-numbered interrupt ID in each group is in the range of the
external combiner, so we only need to code for this in the first of
the two loops in exynos4210_init_board_irqs().
The old code in exynos4210_combiner_get_gpioin() which is being
deleted here had several problems which don't exist in the new code
in its handling of the multi-core timer interrupts:
(1) the case labels specified bits 4 ... 8, but bit '8' doesn't
exist; these should have been 4 ... 7
(2) it used the input irq[EXYNOS4210_COMBINER_GET_IRQ_NUM(1, bit + 4)]
multiple times as the input of several different splitters,
which isn't allowed
(3) in an apparent cut-and-paste error, the cases for all the
multi-core timer inputs used "bit + 4" even though the
bit range for the case was (intended to be) 4 ... 7, which
meant it was looking at non-existent bits 8 ... 11.
None of these exist in the new code.

The combiner_grp_to_gic_id[] array includes the EXT_GIC_ID_MCT_G0
and EXT_GIC_ID_MCT_G1 multiple times. This means that we will
connect multiple IRQs up to the same external GIC input, which
is not permitted. We do the same thing in the code in
exynos4210_init_board_irqs() because the conditionals selecting
an irq_id in the first loop match multiple interrupt IDs.
Overall we do this for interrupt IDs
(1, 4), (12, 4), (35, 4), (51, 4), (53, 4) for EXT_GIC_ID_MCT_G0
and
(1, 5), (12, 5), (35, 5), (51, 5), (53, 5) for EXT_GIC_ID_MCT_G1
These correspond to the cases for the multi-core timer that we are
wiring up to multiple inputs on the combiner in
exynos4210_combiner_get_gpioin(). That code already deals with all
these interrupt IDs being the same input source, so we don't need to
connect the external GIC interrupt for any of them except the first
(1, 4) and (1, 5). Remove the array entries and conditionals which
were incorrectly causing us to wire up extra lines.
This bug didn't cause any visible effects, because we only connect
up a device to the "primary" ID values (1, 4) and (1, 5), so the
extra lines would never be set to a level.

Currently for the interrupts MCT_G0 and MCT_G1 which are
the only ones in the input range of the external combiner
and which are also wired to the external GIC, we connect
them only to the internal combiner and the external GIC.
This seems likely to be a bug, as all other interrupts
which are in the input range of both combiners are
connected to both combiners. (The fact that the code in
exynos4210_combiner_get_gpioin() is also trying to wire
up these inputs on both combiners also suggests this.)
Wire these interrupts up to both combiners, like the rest.

In exynos4210_init_board_irqs(), the loop that handles IRQ lines that
are in a range that applies to the internal combiner only creates a
splitter for those interrupts which go to both the internal combiner
and to the external GIC, but it does nothing at all for the
interrupts which don't go to the external GIC, leaving the
irq_table[] array element empty for those. (This will result in
those interrupts simply being lost, not in a QEMU crash.)
I don't have a reliable datasheet for this SoC, but since we do wire
up one interrupt line in this category (the HDMI I2C device on
interrupt 16,1), this seems like it must be a bug in the existing
QEMU code. Fill in the irq_table[] entries where we're not splitting
the IRQ to both the internal combiner and the external GIC with the
IRQ line of the internal combiner. (That is, these IRQ lines go to
just one device, not multiple.)
This bug didn't have any visible guest effects because the only
implemented device that was affected was the HDMI I2C controller,
and we never connect any I2C devices to that bus.

The exynos4210 code currently has two very similar arrays of IRQs:
* board_irqs is a field of the Exynos4210Irq struct which is filled
in by exynos4210_init_board_irqs() with the appropriate qemu_irqs
for each IRQ the board/SoC can assert
* irq_table is a set of qemu_irqs pointed to from the
Exynos4210State struct. It's allocated in exynos4210_init_irq,
and the only behaviour these irqs have is that they pass on the
level to the equivalent board_irqs[] irq
The extra indirection through irq_table is unnecessary, so coalesce
these into a single irq_table[] array as a direct field in
Exynos4210State which exynos4210_init_board_irqs() fills in.

The phb3/phb4/phb5 root ports inherit from the default PCIE root port
implementation, which requests a LSI interrupt (#INTA). On real
hardware (POWER8/POWER9/POWER10), there is no such LSI. This patch
corrects it so that it matches the hardware.
As a consequence, the device tree previously generated was bogus, as
the root bridge LSI was not properly mapped. On some
implementation (powernv9), it was leading to inconsistent interrupt
controller (xive) data. With this patch, it is now clean.

This patch skips [de]asserting a LSI interrupt if the device doesn't
have any LSI defined. Doing so would trigger an assert in
pci_irq_handler().
The PCIE root port implementation in qemu requests a LSI (INTA), but a
subclass may want to change that behavior since it's a valid
configuration. For example on the POWER8/POWER9/POWER10 systems, the
root bridge doesn't request any LSI.

I'm moving this because next patch will add more code under the ifdef
and it will be cleaner if we keep them together.
Also switch the ifdef branches to make it more convenient to add code
under CONFIG_TCG in the next patch.

All devices raising PSI interrupts are now converted to use GPIO lines
and the pnv_psi_irq_set() routines have become useless. Drop them.

Create an anonymous output GPIO line to connect the LPC device with
the PSIHB device and raise the appropriate PSI IRQ line depending on
the processor model.
A temporary __pnv_psi_irq_set() routine is introduced to handle the
transition. It will be removed when all devices raising PSI interrupts
are converted to use GPIOs.

On HW, the PSI and FSP interrupt levels are muxed under the same
interrupt number. For coding reasons, an extra IRQ number was
introduced to index register values in an array. It increased the
count of IRQs which do not fit in the PSI IRQ range anymore.
The PSI and FSP interrupts should be modeled with an extra level of
GPIO lines but since QEMU does not support them, simply drop the extra
number to stay within the IRQ range.

Inside qemu_log, we perform qemu_log_trylock/unlock, which need
not be done if we have already performed the lock beforehand.
Always check the result of qemu_log_trylock -- only checking
qemu_loglevel_mask races with the acquisition of the lock on
the logfile.

This function can fail, which makes it more like ftrylockfile
or pthread_mutex_trylock than flockfile or pthread_mutex_lock,
so rename it.
To closer match the other trylock functions, release rcu_read_lock
along the failure path, so that qemu_log_unlock need not be called
on failure.
