platform/x86/amd/pmf: Differentiate PMF ACPI versions
For family 1AH, certain PMF features have been enhanced - leading to a
newer APMF (AMD PMF) spec (BIOS and PMF driver interface) called v2.
This information would be fed into the if_version field of the
verify_interface method of the APMF call from the BIOS.
Use this information to store the version number to differentiate
between v1 or v2 and also store the information into the PMF private
data structure, as this information would be required for further code
branching to support the latest silicon.
