Subject: perf pmu: Add const to pmu_events_map.

The pmu_events_map is generated at compile time and used for lookup. For
testing purposes we need to swap the map being used.

Having the pmu_events_map be non-const is misleading as it may be an out
argument.

Make it const and update uses so they work on const too.
