Add support for the Arm Cortex-A520, Cortex-A715, and Cortex-A720 CPU
PMUs. They are straight-forward additions with just new compatible
strings.

Should we catch up on Cortex-X (3 and 4 now) while we're at it?
Cheers,

Yes. I'll add those.
Looking a bit further at this, it seems a bunch of platforms
(including a Cortex-X3 based one) are just using "arm,armv8-pmuv3".
That's supposed to be just for s/w models, but it's not enforceable.
Rob
