The overflow handler needs to read modify write when re-enabling the counter so as not to change the counter value as it may have been changed to ready the next interrupt on overflow. Similarly for interrupting counters metag_pmu_enable_counter needs to leave the counter value unchanged rather than resetting it to zero.
