Using common freq functions with sysfs in PMU (but without taking
forcewake) solves the following issues (a) missing support for MTL (b)
missing support for older generations (prior to Gen6) (c) missing support
for slpc when freq sampling has to fall back to requested freq. It also
makes the PMU code future proof where sometimes code has been updated for
sysfs and PMU has been missed.
