commit fb3f3730e4 added mechanism to generate virtual instruction
exception during instruction decode when virt is enabled.
However in some situations, illegal instruction exception can be raised
due to state of CPU. One such situation is implementing branch tracking.
[1] An indirect branch if doesn't land on a landing pad instruction, then
cpu must raise an illegal instruction exception.
Implementation would raise such expcetion due to missing landing pad inst
and not due to decode. Thus DisasContext must have `virt_inst_excp`
initialized to false during DisasContxt initialization for TB.

As it is now, riscv_compute_fdt_addr() is receiving a dram_base, a
mem_size (which is defaulted to MachineState::ram_size in all boards)
and the FDT pointer. And it makes a very important assumption: the DRAM
interval dram_base + mem_size is contiguous. This is indeed the case for
most boards that use a FDT.
The Icicle Kit board works with 2 distinct RAM banks that are separated
by a gap. We have a lower bank with 1GiB size, a gap follows, then at
64GiB the high memory starts. MachineClass::default_ram_size for this
board is set to 1.5Gb, and machine_init() is enforcing it as minimal RAM
size, meaning that there we'll always have at least 512 MiB in the Hi
RAM area.
Using riscv_compute_fdt_addr() in this board is weird because not only
the board has sparse RAM, and it's calling it using the base address of
the Lo RAM area, but it's also using a mem_size that we have guarantees
that it will go up to the Hi RAM. All the function assumptions doesn't
work for this board.
In fact, what makes the function works at all in this case is a
coincidence. Commit 1a475d39ef introduced a 3GB boundary for the FDT,
down from 4Gb, that is enforced if dram_base is lower than 3072 MiB. For
the Icicle Kit board, memmap[MICROCHIP_PFSOC_DRAM_LO].base is 0x80000000
(2 Gb) and it has a 1Gb size, so it will fall in the conditions to put
the FDT under a 3Gb address, which happens to be exactly at the end of
DRAM_LO. If the base address of the Lo area started later than 3Gb this
function would be unusable by the board. Changing any assumptions inside
riscv_compute_fdt_addr() can also break it by accident as well.
Let's change riscv_compute_fdt_addr() semantics to be appropriate to the
Icicle Kit board and for future boards that might have sparse RAM
topologies to worry about:
- relieve the condition that the dram_base + mem_size area is contiguous,
since this is already not the case today;
- receive an extra 'dram_size' size attribute that refers to a contiguous
RAM block that the board wants the FDT to reside on.
Together with 'mem_size' and 'fdt', which are now now being consumed by a
MachineState pointer, we're able to make clear assumptions based on the
DRAM block and total mem_size available to ensure that the FDT will be put
in a valid RAM address.

A common trend in other archs is to calculate the fdt address, which is
usually straightforward, and then calling a function that loads the
fdt/dtb by using that address.
riscv_load_fdt() is doing a bit too much in comparison. It's calculating
the fdt address via an elaborated heuristic to put the FDT at the bottom
of DRAM, and "bottom of DRAM" will vary across boards and
configurations, then it's actually loading the fdt, and finally it's
returning the fdt address used to the caller.
Reduce the existing complexity of riscv_load_fdt() by splitting its code
into a new function, riscv_compute_fdt_addr(), that will take care of
all fdt address logic. riscv_load_fdt() can then be a simple function
that just loads a fdt at the given fdt address.
We're also taken the opportunity to clarify the intentions and
assumptions made by these functions. riscv_load_fdt() is now receiving a
hwaddr as fdt_addr because there is no restriction of having to load the
fdt in higher addresses that doesn't fit in an uint32_t.

We have a convention in other QEMU boards/archs to name MachineState
pointers as either 'machine' or 'ms'. MachineClass pointers are usually
called 'mc'.
The 'virt' RISC-V machine has a lot of instances where MachineState
pointers are named 'mc'. There is nothing wrong with that, but we gain
more compatibility with the rest of the QEMU code base, and easier
reviews, if we follow QEMU conventions.
Rename all 'mc' MachineState pointers to 'ms'. This is a very tedious
and mechanical patch that was produced by doing the following:
- find/replace all 'MachineState *mc' to 'MachineState *ms';
- find/replace all 'mc->fdt' to 'ms->fdt';
- find/replace all 'mc->smp.cpus' to 'ms->smp.cpus';
- replace any remaining occurrences of 'mc' that the compiler complained
about.
