Will Deacon ca2b497253 arm64: perf: Reject stand-alone CHAIN events for PMUv3 ...

It doesn't make sense for a perf event to be configured as a CHAIN event
in isolation, so extend the arm_pmu structure with a ->filter_match()
function to allow the backend PMU implementation to reject CHAIN events
early.
