[PATCH v4 0/4] Add metric for Arm CMN

[Jing Zhang]

Hi all,

This patch set adds event aliases and metrics for Arm CMN, and expands
Compat's ability to match multiple identifiers and expands event fields
in order to achieve the above capabilities.

If it is no longer necessary to declare the "Compat" or "Unit" value
when the metric is described by event aliases, I will delete "Compat"
and "Unit" in the metric, but keep them for now.

Changes since v3:
- Split the arm CMN and ali_drw PMU patches compare to v3. ali_drw PMU
  related patches are in another patchset.
- "Compat" supports matching multiple identifiers.
- Support more event filed.
- Add alias for part of Arm CMN PMU.
- Fix some bug for CMN metric description.
