This is still not a good approach to adding a new digital audio
interface since it does not create a DAI but instead adds it like an
analogue link (but hooked inside the CPU using the DPCM DAPM hooks).
While this may work right now but will not be robust as the framework is
developed and can cause problems in system integration.

A new DAI should be being added for the S/PDIF interface, this should
fully utilise DPCM but an either/or approach would be OK as a stepping
