smbios: add processor-family option

Browse Source 
For RISC-V the SMBIOS standard requires specific values of the processor
family value depending on the bitness of the CPU.

Add a processor-family option for SMBIOS table 4.

The value of processor-family may exceed 255 and therefore must be provided
in the Processor Family 2 field. Set the Processor Family field to 0xFE
which signals that the Processor Family 2 is used.
