Subject: [PATCH v5 0/3]  powerpc/perf: Add json file support for hv_24x7 core level events

Patchset enhance current runtime parameter support. It introduces new
fields like "PerChip" and "PerCore" similar to the field "PerPkg" which is
used to specify perpkg events. 

The "PerCore" and "PerChip" specifies whether its core or chip events.
Based on which we can decide which runtime parameter user want to
access. Now character  '?' can refers different parameter based on user
requirement.

Initially, every time we want to add new terms like chip, core, thread
etc, we need to create corrsponding fields in pmu_events and event
struct.
This patchset adds an enum called 'aggr_mode_class' which store all these
aggregation like perchip/percore. It also adds new field 'AggregationMode'
to capture these terms.
Now, if user wants to add any new term, they just need to add it in
the enum defined.

Changelog:
v4 -> v5
- Remove intel side changes on uncore events by removing PerPkg
  field from enum "AggregationMode" and other corresponding changes.
