[PATCH v3 0/2] drivers/perf: hisi: Updates for HiSilicon uncore PMUs

[Yushan Wang <wangyushan12@huawei.com>]

This patchset added support of ITS PMU, and new version of MN PMU.

ITS PMU supports counting number and latency of interrupts by
category, and statistics of micro-ops of ITS.

The new version of MN PMU added cycles event, to be used for MN
metric computing.

Changes:
v3:
- Added check_filter callback to refuse new filtered events when there
  are already filtered ones running as per Sashiko.

v2:
- Added int_en filter to tell if int_id is used, enabling filtering
  interrupt with 0 int_id per Sashiko.
- Changed event format width to align with register width per Sashiko.
