Subject: [PATCH v2 10/11] perf vendor events arm64: fixup A53 to use recommended events
This patch fixes the ARM Cortex-A53 json to use event definition
from the ARMv8 recommended events.
The brief description is kept for readability, but is not strictly
required.
In addition to this change, other changes were made:
- remove stray ','
- remove mirrored events in memory.json and bus.json
- fixed indentation to be consistent with other ARM
JSONs
