Robin Murphy 7255cfb199 dt-bindings/perf: Add Arm CoreSight PMU
Add a binding for implementations of the Arm CoreSight Performance
Monitoring Unit Architecture. Not to be confused with CoreSight debug
and trace, the PMU architecture defines a standard MMIO interface for
event counters following a similar design to the CPU PMU architecture,
where the implementation and most of its features are discoverable
through ID registers.
