perf/arm-cmn: Minor event type housekeeping

While handling RN-D nodes under the functionally-identical RN-I type
works fine for perf tool users using the "rnid_" event aliases, and that
is the documented and expected ABI, there's little reason not to be
permissive and accept the actual RN-D type as an additional encoding for
the same events as well. This may be convenient for other tooling
generating event configs directly from its own topology data.

In the RN-I event mood, it also seems as good a time as any to clean up
a forgotten macro for CCLA_RNI events which ended up being unnecessary.
