Message-ID	<[email protected]>

The ADMACs present in M3 series devices (t8122 and t603x SoCs) need
additional register writes in order to function correctly. Add a new
compatible chain for those, and change the driver to do the write.

To simplify the merge strategy, the device tree entries will be sent
in a future patch series.
