drm/i915/pmu: "Frequency" is reported as accumulated cycles

Browse Source 
We report "frequencies" (actual-frequency, requested-frequency) as the
number of accumulated cycles so that the average frequency over that
period may be determined by the user. This means the units we report to
the user are Mcycles (or just M), not MHz.
