simpleperf: add --use-devfreq-counters option. On devices like pixel 3, there are 7 hardware counters in cpu pmu. But 4 of them are used by devfreq to monitor memory latency. In case we need more than 3 counters, add an option to let devfreq release counters. Also add a warning of using this option if it seems we need more counters. Bug: none Test: run simpleperf_unit_test. Change-Id: I9a13716a8b64c8e0fc03a79b0c11dd29da169c56
