This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
We are almost fully converted to QOM after this commit.

Assign the 4 IRQs from the board after device instantiation. This moves

Since 0c90c52fab (ppc_prep: convert to memory
API) OHW was "Trying to execute code outside RAM or ROM at 0xfff00700".
The BIOS MemoryRegion is created with a fixed size of 1 MiB.
Ensure that the full size can be accessed since the exception
vectors are located at 0xfff00000 and the BIOS may want to use them.
It thereby no longer depends on the actual BIOS binary size.

Currently creating a memory region automatically registers it for
live migration. This differs from other state (which is enumerated
in a VMStateDescription structure) and ties the live migration code
into the memory core.
Decouple the two by introducing a separate API, vmstate_register_ram(),
for registering a RAM block for migration. Currently the same
implementation is reused, but later it can be moved into a separate list,
and registrations can be moved to VMStateDescription blocks.

There is nothing in the i8259 spec that justifies the special
pic_intack_read. At least the Linux PREP kernels configure the PICs
properly so that pic_read_irq returns identical values, and setting
read_reg_select in PIC0 cannot be derived from any special i8259 mode.
So switch ppc_prep to pic_read_irq and drop the now unused PIC code.

This was done with:

$(git grep -l 'qemu_get_clock\>' )
sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
$(git grep -l 'qemu_new_timer\>' )
after checking that get_clock and new_timer never occur twice
on the same line. There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.
There was exactly one false positive in qemu_run_timers:
- current_time = qemu_get_clock (clock);
+ current_time = qemu_get_clock_ns (clock);
which is of course not in this patch.

r3480 added this check to account for the entry vector 0xfff00100 to be
available for CPUs that need it. Today however, the NIP is not yet
initialized at this point (zero), so the check always triggers.
Moreover, BIOS size check is already done previously, so this part can
be removed too.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

Allow the intercept the RTC IRQ for the HPET legacy mode. Then push
routing to IRQ8 completely into the HPET. This allows to turn
hpet_in_legacy_mode() into a private function. Furthermore, this stops
the RTC from clearing IRQ8 even if the HPET is in control.
This patch comes with a side effect: The RTC timers will no longer be
stoppend when there is no IRQ consumer, possibly causing a minor
performance degration. But as the guest may want to redirect the RTC to
the SCI in that mode, it should normally disable unused IRQ source
anyway.

pci_nic_init_nofail(), which behaves just like pci_nic_init() used to
