Add Support for HiSilicon CPA PMU driver. Json file in perf tool
is applied in 
https://lore.kernel.org/linux-arm-kernel/YhkhSZp+a715Ldzr@kernel.org/.

Change since v4:
- Add hisi_cpa_pmu_enable_pm() for a failed probe.
- Link: https://lore.kernel.org/linux-arm-kernel/20220407124617.54521-1-liuqi115@huawei.com/

Change since v3:
- Add more explanation for changing CPA PMUs CPU affinity.
- Address the comments from John.
- Link: https://lore.kernel.org/linux-arm-kernel/20220321070124.41338-1-liuqi115@huawei.com/

Change since v2:
- Associate CPA PMUs with CPUs online, rather than CPUs in the nearest SCCL.
- Move CPA power management to probe and remove function.
- Address the comments from John.
- Link: https://lore.kernel.org/linux-arm-kernel/20220224111129.41416-1-liuqi115@huawei.com/
