We extend virt machine to emulate both AIA IMSIC and AIA APLIC
devices only when "aia=aplic-imsic" parameter is passed along
with machine name in the QEMU command-line. The AIA IMSIC is
only a per-HART MSI controller so we use AIA APLIC in MSI-mode
to forward all wired interrupts as MSIs to the AIA IMSIC.
We also provide "aia-guests=<xyz>" parameter which can be used
to specify number of VS-level AIA IMSIC Guests MMIO pages for
each HART.

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

We extend RISC-V virt machine to allow creating a multi-socket
machine. Each RISC-V virt machine socket is a NUMA node having
a set of HARTs, a memory instance, a CLINT instance, and a PLIC
instance. Other devices are shared between all sockets. We also
update the generated device tree accordingly.
By default, NUMA multi-socket support is disabled for RISC-V virt
machine. To enable it, users can use "-numa" command-line options
of QEMU.
Example1: For two NUMA nodes with 2 CPUs each, append following
to command-line options: "-smp 4 -numa node -numa node"
Example2: For two NUMA nodes with 1 and 3 CPUs, append following
to command-line options:
"-smp 4 -numa node -numa node -numa cpu,node-id=0,core-id=0 \
-numa cpu,node-id=1,core-id=1 -numa cpu,node-id=1,core-id=2 \
-numa cpu,node-id=1,core-id=3"
The maximum number of sockets in a RISC-V virt machine is 8
but this limit can be changed in future.

Back in 2016, we discussed[1] rules for headers, and these were
generally liked:
1. Have a carefully curated header that's included everywhere first. We
got that already thanks to Peter: osdep.h.
2. Headers should normally include everything they need beyond osdep.h.
If exceptions are needed for some reason, they must be documented in
the header. If all that's needed from a header is typedefs, put
those into qemu/typedefs.h instead of including the header.
3. Cyclic inclusion is forbidden.
This patch gets include/ closer to obeying 2.
It's actually extracted from my "[RFC] Baby steps towards saner
headers" series[2], which demonstrates a possible path towards
checking 2 automatically. It passes the RFC test there.

This patch fixes four different things, to maintain bisectability they
have been merged into a single patch. The following fixes are below:
sifive_plic: Fix incorrect irq calculation
The irq is incorrectly calculated to be off by one. It has worked in the
past as the priority_base offset has also been set incorrectly. We are
about to fix the priority_base offset so first first the irq
calculation.
sifive_u: Fix PLIC priority base offset and numbering
According to the FU540 manual the PLIC source priority address starts at
an offset of 0x04 and not 0x00. The same manual also specifies that the
PLIC only has 53 source priorities. Fix these two incorrect header
files.
We also need to over extend the plic_gpios[] array as the PLIC sources
count from 1 and not 0.
riscv: sifive_e: Fix PLIC priority base offset
According to the FE31 manual the PLIC source priority address starts at
an offset of 0x04 and not 0x00.
riscv: virt: Fix PLIC priority base offset
Update the virt offsets based on the newly updated SiFive U and SiFive E
offsets.

Removes a whole lot of unnecessary boilerplate code. Machines
don't need to be objects. The expansion of the SOC object model
for the RISC-V machines will happen in the future as SiFive
plans to add their FE310 and FU540 SOCs to QEMU. However, it
seems that this present boilerplate is complete unnecessary.
