James Hogan c6ac1e6eda metag: perf: add missing prev_count updates ... The prev_count needs setting when changing the counter value, otherwise the calculated delta will be wrong, which for frequency sampling (dynamic period sampling) results in sampling at too high a frequency. For non-interrupting performance counters it should also be cleared when enabling the counter since the write to the PERF_COUNT register will clear the perf counter. This also includes a minor change to remove the u64 cast from the metag_pmu->write() call as metag_pmu->write() takes a u32 anyway, and in any case GCC is smart enough to optimise away the cast.
