perf/arm-ni: Add NoC S3 support

NoC S3 and its SI L1 sibling look largely similar to their predecessors,
but add the notion of subfeatures to the discovery process, which we now
use to find the event muxes for each device node. Plus, as ever, more
mildly annoying shuffling around of some of the PMU registers (this time
it's the counters...)
