A machine driver should be for a particular machine, describing how the
various components have been connected on that particular machine.  This
looks like you're trying to do a single machine driver for all systems.

Probably this should have some sort of name indicating that it's for use
with systems that are trying to do something using the BIOS scheme
you've got for these systems; I'd expect that if the systems get much
traction in the market you'll also end up with systems implementing
regular ASoC machine drivers too.

Here and through most of the rest of the driver you need to namespace
stuff more.
