hw/riscv: Use the CPU to determine if 32-bit

Browse source 
Instead of using string compares to determine if a RISC-V machine is
using 32-bit or 64-bit CPUs we can use the initalised CPUs. This avoids
us having to maintain a list of CPU names to compare against.

This commit also fixes the name of the function to match the
riscv_cpu_is_32bit() function.
