Log:
  MFC 308005: Add powerd(8) support for several families of AMD CPUs.

  Use the same logic to calculate the nominal CPU frequency from the P-state
  MSRs on family 0x12, 0x15, and 0x16 CPUs as is used for family 0x10.
  Family 0x14 was included in the original patch in the PR but I left that
  out as the BIOS writer's guide for family 0x14 CPUs show a different layo=
ut
  for the relevant MSR and include a different formulate for calculating the
  frequency.

  While here, simplify a few expressions and print out the family of
  unsupported CPUs in hex rather than decimal.
