arm64: perf: Reject stand-alone CHAIN events for PMUv3
commit ca2b497253ad01c80061a1f3ee9eb91b5d54a849 upstream.
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.
