hw/riscv/virt.c: remove 'is_32_bit' param from create_fdt_socket_cpus()

Browse source 
create_fdt_socket_cpus() writes a different 'mmu-type' value if we're
running in 32 or 64 bits. However, the flag is being calculated during
virt_machine_init(), and is passed around in create_fdt(), then
create_fdt_socket(), and then finally create_fdt_socket_cpus(). None of
the intermediate functions are using the flag, which is a bit
misleading.

Remove 'is_32_bit' flag from create_fdt_socket_cpus() and calculate it
using the already available RISCVVirtState pointer. This will also
change the signature of create_fdt_socket() and create_fdt(), making it
clear that these functions don't do anything special when we're running
in 32 bit mode.
