Subject: [PATCH 04/20] perf vendors events arm64: Arm Cortex-A9

Add PMU events for Arm Cortex-A9
Update mapfile.csv

Event data based on:
https://github.com/ARM-software/data/tree/master/pmu/cortex-a9.json

which is based on PMU event descriptions from the Arm Cortex-A9 Technical
Reference Manual.

Mapping data (for mapfile.csv) based on:
https://github.com/ARM-software/data/blob/master/cpus.json

which is based on Main ID Register (MIDR) information found in the Arm
Technical Reference Manuals for individual CPUs.
