drivers/perf: hisi: Enable HiSilicon Erratum 162700402 quirk for HIP09

HiSilicon UC PMU v2 suffers the erratum 162700402 that the PMU counter
cannot be set due to the lack of clock under power saving mode. This will
lead to error or inaccurate counts. The clock can be enabled by the PMU
global enabling control.

This patch tries to fix this by set the UC PMU enable before set event
period to turn on the clock, and then restore the UC PMU configuration.
The counter register can hold its value without a clock.

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].
