Frequency sampling mode dynamically adjusts the sample period so as to hit a particular frequency of samples. The sample period starts at just 1 and then gets increased if the interrupt rate is too high. This changed sample period needs handling in metag_pmu_event_set_period to update period_left (as the ARM equivalent does). The calculated delta also needs subtracting from period_left in metag_pmu_event_update in order to hit the conditional blocks in metag_pmu_event_set_period which update last_period (which is used in the dynamic sampling period calculation).
