platform/x86/amd/pmf: Handle AMT and CQL events for Auto mode
The transition to auto-mode happens when the PMF driver receives
AMT (Auto Mode transition) event. transition logic will reside in the
PMF driver but the events would come from other supported drivers[1].
The thermal parameters would vary between when a performance "on-lap" mode
is detected and versus when not. The CQL event would get triggered from
other drivers, so that PMF driver would adjust the system thermal config
based on the ACPI inputs.
OEMs can control whether or not to enable AMT or CQL via other supported
drivers[1] but the actual transition logic resides in the AMD PMF driver.
When an AMT event is received the automatic mode transition RAPL algorithm
will run. When a CQL event is received an performance "on-lap" mode will
be enabled and thermal parameters will be adjusted accordingly.
