perf/arm_dsu: Support DSU-120
DSU-120 has the same system register interface as previous DSUs, but
no longer offers a dedicated cycle counter. While this is not directly
discoverable via PMCR, the PMCCNTR register is still defined to exist
with RAZ/WI behaviour, allowing for a straightforward heuristic.
