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.
