Move arm64's MMU notifier trace events into common code in preparation for doing the hva->gfn lookup in common code. The alternative would be to trace the gfn instead of hva, but that's not obviously better and could also be done in common code. Tracing the notifiers is also quite handy for debug regardless of architecture. Remove a completely redundant tracepoint from PPC e500.
