[PATCH v7 3/4] perf utils: Add helper function is_pmu_core to detect PMU CORE devices

On some platforms, PMU core devices sysfs name is not cpu. Adding function is_pmu_core to detect PMU core devices using core device specific hints in sysfs. For arm64 platforms, all core devices have file "cpus" in sysfs. Acked-by: Will Deacon Tested-by: Shaokun Zhang Signed-off-by:
