dt-bindings: perf: arm-cmn: Add CMN S3

The CMN S3 PMU is functionally still very similar to CMN-700, however
while the register contents are compatible, many of them are moved to
different offsets. While this is technically discoverable by a careful
driver that understands the part number in the peripheral ID registers
(which do at least remain in the same place), a new unique compatible
seems warranted to avoid any surprises.
