[PATCH 06/17] dt-bindings: arm-pmu: Add PMU compatible strings for Apple M2 cores

The PMUs on the avalanche and blizzard CPU two micro-architectures are
mostly compatible with M1 ones. They miss support for a single counter
according to Apple's PMU counter list.

Signed-off-by: Janne Grunau <j at jannau.net>

This trivial dt-bindings update should be merged through the asahi-soc
tree to ensure validation of the Apple M2 (t8112) devicetrees in this
series.

The necessary driver update will be sent separately.
