Zone transition handling and resource management is open coded (and
semi-duplicated in the case of open, close and finish).
In preparation for Simple Copy command support (which also needs to open
zones for writing), consolidate into a set of 'nvme_zrm' functions and
in the process fix a bug with the controller not closing an open zone to
allow another zone to be explicitly opened.

nvme-ns device is registered to a nvme controller device during the
initialization in nvme_register_namespace() in case that 'bus' property
is given which means it's mapped to a single controller.
This patch introduced a new property 'subsys' just like the controller
device instance did to map a namespace to a NVMe subsystem.
If 'subsys' property is given to the nvme-ns device, it will belong to
the specified subsystem and will be attached to all controllers in that
subsystem by enabling shared namespace capability in NMIC(Namespace
Multi-path I/O and Namespace Capabilities) in Identify Namespace.
Usage:
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
-device nvme,serial=bar,id=nvme1,subsys=subsys0
-device nvme,serial=baz,id=nvme2,subsys=subsys0
-device nvme-ns,id=ns1,drive=<drv>,nsid=1,subsys=subsys0 # Shared
-device nvme-ns,id=ns2,drive=<drv>,nsid=2,bus=nvme2 # Non-shared
In the above example, 'ns1' will be shared to 'nvme0' and 'nvme1' in
the same subsystem. On the other hand, 'ns2' will be attached to the
'nvme2' only as a private namespace in that subsystem.
All the namespace with 'subsys' parameter will attach all controllers in
the subsystem to the namespace by default.

We have nvme-subsys and nvme devices mapped together. To support
multi-controller scheme to this setup, controller identifier(id) has to
be managed. Earlier, cntlid(controller id) used to be always 0 because
we didn't have any subsystem scheme that controller id matters.
This patch introduced 'cntlid' attribute to the nvme controller
instance(NvmeCtrl) and make it allocated by the nvme-subsys device
mapped to the controller. If nvme-subsys is not given to the
controller, then it will always be 0 as it was.
Added 'ctrls' array in the nvme-subsys instance to manage attached
controllers to the subsystem with a limit(32). This patch didn't take
list for the controllers to make it seamless with nvme-ns device.

nvme controller(nvme) can be mapped to a NVMe subsystem(nvme-subsys).
This patch maps a controller to a subsystem by adding a parameter
'subsys' to the nvme device.
To map a controller to a subsystem, we need to put nvme-subsys first and
then maps the subsystem to the controller:
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
If 'subsys' property is not given to the nvme controller, then subsystem
NQN will be created with serial (e.g., 'foo' in above example),
Otherwise, it will be based on subsys id (e.g., 'subsys0' in above
example).

The mps2-tz code uses PPCPortInfo data structures to define what
devices are present and how they are wired up. Currently we use
these to specify device types and addresses, but hard-code the
interrupt line wiring in each make_* helper function. This works for
the two boards we have at the moment, but the AN524 has some devices
with different interrupt assignments.
This commit adds the framework to allow PPCPortInfo structures to
specify interrupt numbers. We add an array of interrupt numbers to
the PPCPortInfo struct, and pass it through to the make_* helpers.
The following commit will change the make_* helpers over to using the
framework.

On the MPS2 boards, the first 32 interrupt lines are entirely
internal to the SSE; interrupt lines for devices outside the SSE
start at 32. In the application notes that document each FPGA image,
the interrupt wiring is documented from the point of view of the CPU,
so '0' is the first of the SSE's interrupts and the devices in the
FPGA image itself are '32' and up: so the UART 0 Receive interrupt is
32, the SPI #0 interrupt is 51, and so on.
Within our implementation, because the external interrupts must be
connected to the EXP_IRQ[0...n] lines of the SSE object, we made the
get_sse_irq_in() function take an irqno whose values start at 0 for
the first FPGA device interrupt. In this numbering scheme the UART 0
Receive interrupt is 0, the SPI #0 interrupt is 19, and so on.
The result of these two different numbering schemes has been that
half of the devices were wired up to the wrong IRQs: the UART IRQs
are wired up correctly, but the DMA and SPI devices were passing
start-at-32 values to get_sse_irq_in() and so being mis-connected.
Fix the bug by making get_sse_irq_in() take values specified with the
same scheme that the hardware manuals use, to avoid confusion.

The AN524 version of the SCC interface has different behaviour for
some of the CFG registers; implement it.
Each board in this family can have minor differences in the meaning
of the CFG registers, so rather than trying to specify all the
possible semantics via individual device properties, we make the
behaviour conditional on the part-number field of the SCC_ID register
which the board code already passes us.
For the AN524, the differences are:
* CFG3 is reserved rather than being board switches
* CFG5 is a new register ("ACLK Frequency in Hz")
* CFG6 is a new register ("Clock divider for BRAM")
We implement both of the new registers as reads-as-written.

The AN524 has more interrupt lines than the AN505 and AN521; make
numirq board-specific rather than a compile-time constant.
Since the difference is small (92 on the current boards and 95 on the
new one) we don't dynamically allocate the cpu_irq_splitter[] array
but leave it as a fixed length array whose size is the maximum needed
for any of the boards.

In the mps2-tz board code, we handle devices whose interrupt lines
must be wired to all CPUs by creating IRQ splitter devices for the
AN521, because it has 2 CPUs, but wiring the device IRQ directly to
the SSE/IoTKit input for the AN505, which has only 1 CPU.
We can avoid making an explicit check on the board type constant by
instead creating and using the IRQ splitters for any board with more
than 1 CPU. This avoids having to add extra cases to the
conditionals every time we add new boards.

per-board, rather than relying on the defaults. The AN505 and AN521

We were previously using the default OSCCLK settings, which are
correct for the older MPS2 boards (mps2-an385, mps2-an386,
mps2-an500, mps2-an511), but wrong for the mps2-an505 and mps2-511
implemented in mps2-tz.c. Now we're setting the values explicitly we
can fix them to be correct.

Currently the MPS2 SCC device implements a fixed number of OSCCLK
values (3). The variant of this device in the MPS3 AN524 board has 6
OSCCLK values. Switch to using a PROP_ARRAY, which allows board code
to specify how large the OSCCLK array should be as well as its
values.
With a variable-length property array, the SCC no longer specifies
default values for the OSCCLKs, so we must set them explicitly in the
board code. This defaults are actually incorrect for the an521 and
an505; we will correct this bug in a following patch.
This is a migration compatibility break for all the mps boards.

For a long time now the UI layer has guaranteed that the console
surface is always 32 bits per pixel, RGB. The TCX code already
assumes 32bpp, but it still has some checks of is_surface_bgr()
in an attempt to support 32bpp BGR. is_surface_bgr() will always
return false for the qemu_console_surface(), unless the display
device itself has deliberately created an alternate-format
surface via a function like qemu_create_displaysurface_from().
Drop the never-used BGR-handling code, and assert that we have
a 32-bit surface rather than just doing nothing if it isn't.
