The mem_events can be retrieved from the struct perf_pmu now. An ARCH specific perf_mem_events__ptr() is not required anymore. Remove all of them. The Intel hybrid has multiple mem-events-supported PMUs. But they share the same mem_events. Other ARCHs only support one mem-events-supported PMU. In the configuration, it's good enough to only configure the mem_events for one PMU. Add perf_mem_events_find_pmu() which returns the first mem-events-supported PMU. In the perf_mem_events__init(), the perf_pmus__scan() is not required anymore. It avoids checking the sysfs for every PMU on the system. Make the perf_mem_events__record_args() more generic. Remove the perf_mem_events__print_unsupport_hybrid(). Since pmu is added as a new parameter, rename perf_mem_events__ptr() to perf_pmu__mem_events_ptr(). Several other functions also do a similar rename.
