perf/arm-cmn: Refactor event filter programming

Browse source

We're soon going to need to cope with events having multiple filters,
plus the filter fields themselves moving around, wherein any more inline
if/else logic will struggle to scale. Add a more general abstraction for
the node-specific filter controls, and rejig the pmu_event_sel filter
programming around it in a more extensible manner.
