[0/2] drm/i915/pmu: Use common freq functions with sysfs

Message

Expose intel_rps_read_actual_frequency_fw to read the actual freq without
taking forcewake for use by PMU. The code is refactored to use a common set
of functions across sysfs and PMU. Using common functions with sysfs in PMU
solves the issues of missing support for MTL and missing support for older
generations (prior to Gen6). It also future proofs the PMU where sometimes
code has been updated for sysfs and PMU has been missed.
