Add support for HiSilicon UC/H60PA/PAv3 PMU driver.

PAv3 PMU: Compared with the PAv2 PMU, the PAv3 PMU has different event.
The PAv3 PMU removed some events which are supported by PAv2 PMU. The
older PA PMU driver will probe v3 as v2. Add the HISI0275 HID for PAv3
PMU to distinguish different.

H60PA PMU: The H60PA PMU and PA are two different devices. The H60PA PMU
supports higher bandwidth, and the PA PMU delay is relatively low.
Different HIDs are used to distinguish the delay.

UC PMU: Each cluster is integrated with a unified cache (UC) PMU, which
provides consistency between NUMA and UMA domains. It sits between
L2 and the memory system.

Change since v4:
- Add new HID to distinguish PAv2 and PAv3 according to Mark's suggestion.

Change since v3:
- Modify the UC PMU patch commit message according to Jonathan's comment.

Change since v2:
- Modify the driver description according to Jonathan's comment.

Change since v1:
- Improve according to Yicong's suggestion
- Fixes build warning of "-Wmissing-prototypes"
