The implemented Cortex A57 events are not A57 specific.
They are recommended by ARM and can be found on other
ARMv8 SOCs like Cavium ThunderX too. Therefore move
these events to the common PMUv3 table.

I can't find anything in the architecture that suggests these event
numbers are necessarily portable between implementations. Am I missing
something?

Aha, I just noticed appendix K3.1 (silly me for missing it...).

Lemme check whether or not that mandates that those encodings can't be
used for wildly different things.
