To: linux-arm-kernel
The complete common architectural and micro-architectural
event number structure is filtered based on PMCEIDn_EL0 and
copied to a new structure which is exposed to /sys
The function which derives event bitmap from PMCEIDn_EL0 is
executed in the cpus, which has the pmu being initialized,
for heterogeneous pmu support.
Enforced armv8_pmuv3_event_attrs array for event number
ordering as this is indexed with event number now.

Broadcom Vulcan uses ARMv8 PMUv3 and supports most of
the ARMv8 recommended implementation defined events.
Added Vulcan events mapping for perf and perf_cache map.
