ARM: perf: Only reset PMxEVCNTCR registers on reset
The Krait specific PMxEVCNTCR register is unpredictable upon reset. Currently we clear the register before we setup an event, but we don't need to do that. Instead, we can iterate through all the events and clear them once when we reset the PMU, saving a write in the event setup path.
