After nine generations of adding to model specific list of CPUs that support PPIN (Protected Processor Inventory Number) Intel allocated a CPUID bit to enumerate the MSRs. CPUID(EAX=7, ECX=1).EBX bit 0 enumerates presence of MSR_PPIN_CTL and MSR_PPIN. Add it to the "scattered" CPUID bits and add an entry to the ppin_cpuids[] x86_match_cpu() array to catch Intel CPUs that implement it.
