Junhao He 312eca95e2 drivers/perf: hisi: Add support for HiSilicon UC PMU driver
On HiSilicon Hip09 platform, there are 4 UC (unified cache) modules
on each chip CCL (CPU Cluster). UC is a cache that provides
coherence between NUMA and UMA domains. It is located between L2
and Memory System. Many PMU events are supported. Let's support
the UC PMU driver using the HiSilicon uncore PMU framework.

* rd_req_en : rd_req_en is the abbreviation of read request tracetag
enable and allows user to count only read operations. Details are listed
in the hisi-pmu document at Documentation/admin-guide/perf/hisi-pmu.rst

* srcid_en & srcid: Allows users to filter statistical information based
on specific CPU/ICL by srcid.
srcid_en depends on rd_req_en being enabled.

* uring_channel: Allows users to filter statistical information based on
the specified tx request uring channel.
uring_channel only supported events: [0x47 ~ 0x59].
