platform/x86/amd/pmf: Add support to notify sbios heart beat event
Add support for newer revision of the heart beat notify events.
This event is used to notify to the OEM BIOS on driver
load/unload/suspend/resume scenarios.
If OEM BIOS does not receive the heart beat event from PMF driver, OEM
BIOS shall conclude that PMF driver is no more active and BIOS will
update to the legacy system power thermals.
