Madhavan Srinivasan b58064da04 powerpc/perf: Infrastructure to support addition of blacklisted events
Introduce code to support addition of blacklisted events for a
processor version. Blacklisted events are events that are known to not
count correctly on that CPU revision, and so should be prevented from
being counted so as to avoid user confusion.

A 'pointer' and 'int' variable to hold the number of events are added
to 'struct power_pmu', along with a generic function to loop through
the list to validate the given event. Generic function
'is_event_blacklisted' is called in power_pmu_event_init() to detect
and reject early.
