-------------------------------------

Intel-SIG: commit 97a5e801b304 ("platform/x86/intel/ifs: Store IFS generation number")
Backport to support IFS SAF & Array BIST on GNR & SRF

-------------------------------------

IFS generation number is reported via MSR_INTEGRITY_CAPS.  As IFS
support gets added to newer CPUs, some differences are expected during
IFS image loading and test flows.

Define MSR bitmasks to extract and store the generation in driver data,
so that driver can modify its MSR interaction appropriately.
