cpu: riscv: set correct SMBIOS processor family value
The SMBIOS specification requires to set the processor family in the type 4
(Processor Information) table to specific values depending only on the
bitness of the system (0x200 for RV32 and 0x201 for RV64).
With this patch dmidecode shows
Handle 0x0004, DMI type 4, 48 bytes
Processor Information
Socket Designation: Not Specified
Type: Central Processor
Family: RV64
for qemu-riscv64_smode_defconfig.
