Change subject: soc/xeon_sp: Read PPIN MSR and save to an array for each CPU
......................................................................

Patch Set 1:

Reading MSR for a remote CPU socket seems not available in coreboot, so piggyback on xeon_sp_core_init() that gets to run on each CPU core and read their MSRs. May not be the best way
to do it, maybe rely on FSP to report PPIN via HOB is another option.
