Shyam Sundar S K b9ab888b4e platform/x86/amd/pmf: Add heartbeat signal support
PMF driver can send periodic heartbeat signals to OEM BIOS. When BIOS does
not receive the signal after a period of time, it can infer that AMDPMF
has hung or failed to load.

In this situation, BIOS can fallback to legacy operations. OEM can modify
the time interval of the signal or completely disable signals through
ACPI Method.
