perf/arm-cmn: Refactor event filter data

Browse source

The ABI hole I have dug myself into requires the driver to know which
event encodings are associated with which particular filter control.
Since we will soon have a notion of multiple filters per event, refactor
the event data to encapsulate filters in an explicit structure, which
can then more easily scale as an array in future.
