perf: arm_cspmu: Reject events meant for other PMUs

Coresight PMU driver didn't reject events meant for other PMUs.
This caused some of the Core PMU events disappearing from
the output of "perf list". In addition, trying to run e.g.

     $ perf stat -e r2 sleep 1

made Coresight PMU driver to handle the event instead of letting
Core PMU driver to deal with it.
