Changelog v2->v3
- Correcting copy-paste typo: this commit adds compatible string for CCN-512
  and not for CCN-502 which has already a support for.
- Now *for real* change the subject to reflect where the driver got moved
  to (drivers/perf) from (drivers/bus).
Changelog v1->v2:
- Change the subject to reflect where the driver got moved to (drivers/perf)
  from (drivers/bus).
- Add credit to my work mate that helped me validate the counts from
  the interconnect.
