Log:
intel-ucode-split: list platform ids based on processor_flags
The Intel CPU "Platform Id" is a 3-bit integer reported by a given MSR.
Intel microcode updates have an 8-bit field to indicate Platform Id
compatibility - one bit in the mask for each of the possible Platform Id
values. To simplify interpretation, report the Platform Id mask also as
a list.
