Patrick Rudolph b01ac7e264 cpu/intel/common: Fill cpu voltage in SMBIOS tables 
Introduce a weak function to let the platform code provide the processor
voltage in 100mV units.

Implement the function on Intel platforms using the MSR_PERF_STATUS msr.
On other platforms the processor voltage still reads as unknown.

Tested on Intel CFL. The CPU voltage is correctly advertised.
