arm: perf: armv7: condense event maps
Now that we have macros for declaring fully invalid event maps, put them to work for all the ARMv7 PMU event maps. While this necessitates repeating common indices, we no longer need to refer to *_UNSUPPORTED events at all, and it makes it possible for the even maps to fit on a single page on a reasonably sized monitor.
