On newer Intel silicon, more IP counters are being added in Intel Platform
Monitoring Technology (PMT) telemetry spaces hosted in MMIO. There is a
need for the intel_pmc_core driver and other drivers to access PMT hosted
telemetry in the kernel using an API. This patchset adds driver APIs to
allow registering and reading telemetry entries. It makes changes to the
intel_pmc_core driver to use these interfaces to access the low power mode
counters that are now exclusively available from PMT.
