Cleaned up event naming convention as per ARM ARM.

Added macros for complete ARMv8 recommended implementation defined events.

Common architectural and micro-architectural events which are exported to /sys
are now filtered using PMCEIDn_EL0

Added support for Broadcom Vulcan PMU.

changes since v2 [2]:
 * Changed event filtering mechanism to use is_visible function pointer
   of attribute_group instead of copying to a new events attribute 
   structure as per Mark's review comments.

changes since v1 [1]:
 Incorporated the following review comments from Will.
 * cleaned up event naming convention as per ARM ARM
 * Filtered common events based on PMCEIDn_EL0
 * Removed exposing implementation defined events to /sys.

From: Ashok Kumar @ 2016-03-28 12:23 UTC (permalink / raw)
  To: linux-arm-kernel

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.

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.

I have incorporated your review comments from v1 and v2. 

I am going to post v4 for fixing the devicetree binding documentation patch

If you have any comments, I can fix it and post with v4.

Thanks,
Ashok
