Subject: [PATCH v4 3/5] perf jevents: Add support for parsing perchip/percore events

Added the "PerChiip" field  in enum "aggr_mode_classs" so that perf
knows they are per chip events.

Added the "PerCore" field in enum "aggr_mode_class" so that perf
knows they are per core events.

Similar to the way we had "PerPkg field to specify perpkg events.
