dt-bindings: arm-pmu: Add PMU compatible strings for Apple M2 cores
The PMUs on the Apple M2 cores avalanche and blizzard CPU are compatible with M1 ones. As on M1 we don't know exactly what the counters count so use a distinct compatible for each micro-architecture. Apple's PMU counter description omits a counter for M2 so there is some variation on the interpretation of the counters. Signed-off-by:Janne Grunau <j@jannau.net> Acked-by:
