Ashok Kumar 4b1a9e6934 arm64/perf: Filter common events based on PMCEIDn_EL0 ...

The complete common architectural and micro-architectural
event number structure is filtered based on PMCEIDn_EL0 and
exposed to /sys using is_visibile function pointer in events
attribute_group.
To filter the events in is_visible function, pmceid based bitmap
is stored in arm_pmu structure and the id field from
perf_pmu_events_attr is used to check against the bitmap.

The function which derives event bitmap from PMCEIDn_EL0 is
executed in the cpus, which has the pmu being initialized,
for heterogeneous pmu support.
