arm64: dts: qcom: Split PMU nodes for heterogeneous CPUs

Arm heterogeneous configurations should have separate PMU nodes for each
CPU uarch as the uarch specific events can be different. The
"arm,armv8-pmuv3" compatible is also intended for s/w models rather than
specific uarch implementations.

All the kryo CPUs are missing PMU compatibles, so they can't be fixed.
