We might end up doing that but as this adaption of the DMA controller to
the audio stack isn't really hardware so much as an implementation
detail of the audio stack it'd be nice to come up with some neater way
of doing it, ideally not involving the platform device at all.

I'm starting to think we should have a framework thing that lets DAI
drivers say they're a combined DMA/DAI driver for cases like this where
there is a generic DMA device that's being shared by lots of different
subsystems.  It's a common situation and it makes the device registration
clearer.  Adding Stephen Warren as he was thinking about this stuff in
the context of the nVidia drivers.
