Ideally your platform would also register the devices separately
(especialy the CODEC which would usually be instantiated by whatever
bus it's on, or the probe of the core driver for the CODEC if it's an
MFD like yours are in silicon) but if you're limited in this way then
it's a good approach.
It may be worth separating out the device registration from the rest of
the machine driver for clarity.
