Subject: [PATCH] perf: pmuv3: Remove comments from armv8pmu_[enable|disable]_event()
The comments in armv8pmu_[enable|disable]_event() are blindingly obvious,
and does not contribute in making things any better. Let's drop them off.
Functional change is not intended.

This change is taken from BRBE V13 series [PATCH 05/10] just to keep the
