[PATCH v2 0/4] perf vendor events arm64: Some tidy-up/refactoring

There is much event duplication in the common and uarch events for A76
and Ampere eMag support, so factor out into a common JSON.

Since the wording for events may differ between CPU datasheet and
the architecture reference manual, the current wording is kept. This
is unless there are minor differences. In addition, event names are
renamed to be same as architecture reference manual, to keep commonality.

Also a minor fix is included for the Ampere eMag JSON.

Differences to v1:
- tidy some ',' misplaced
