drm/i915/pmu: Clear the previous sample value when parking
When turning off the engines, and the pmu sampling, clear the previous
value as the current measurement should be 0.
v2: Use a for-loop
v3:
* Move clearing to timer self-dis-arm to avoid race with parking.
* Clear frequency samples as well.
v4:
* Init frequency to idle_freq. (Chris Wilson)
