drm/i915/pmu: "Frequency" is reported as accumulated cycles
commit add3eeed3683e2636ef524db48e1a678757c8e96 upstream.
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.
