I think that we need to the same here as the IMPDEF recommended events - 
add a common JSON to reduce the duplication.

I had done work on this for current CPUs, but never got it finished. Let 
me check the status.

Ps, arm have put JSONs here for their cores:

But unfortunately the schema does not suit perf.

I raised an issue, but no response.

I'm just wondering if you hand copied the JSON data.
