Subject: [PATCH v2 0/2] perf vendor events: Arm Neoverse N2

This patch series adds the ability for perf to recognise the Arm
Neoverse N2 core and what counters are available.

The first patch adds the new counters to the common and microarch json
file (because they can also exist in other ArmV8 and ArmV9 cpus) Files
are also added to pmu-events/arch/arm64/arm/neoverse-n2 so that 'perf list'
categorises the counters.

The second patch renames armv8-common-and-microarch.json and
armv8-recommended.json, removing the armv8 prefix to reflect that
they can include counters for armv9.

Changes in v2:
 - Addition of a cover letter
 - Small changes in commit messages
 - Omission of a patch reformatting whitespace that was
   applied by Arnaldo
