platform/x86/amd/pmf: Get performance metrics from PMFW

PMF driver polls for metrics information from PMFW to understand the system

This metrics table information will be used the PMF features to tweak the
thermal heuristics. The poll duration can also be changed by the user
by changing the poll duration time.
