hw/riscv/virt.c: rename MachineState 'mc' pointers to 'ms'

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.
