perf/arm-cmn: Support CMN-600AE

Browse source

[ Upstream commit 12a94953c3 ]

The functional safety features of CMN-600AE have little to no impact on
the PMU relative to the base CMN-600 design, so for simplicity we can
reasonably just treat it as the same thing. The only obvious difference
is that the revision numbers aren't aligned, so we may hide some aliases
for events which do actually exist, but those can still be specified via
the underlying "type,eventid" format so it's not too big a deal.
