powerpc, perf: Fix frequency calculation for overflowing counters (FSL version)
When fixing the frequency calculations for perf on powerpc I
forgot to fix the FSL version.
If we dont set event->hw.last_period the frequency to period
calculations in perf go haywire and we continually
throttle/unthrottle the PMU.
