I think we're still missing some code for SOF that implements the
machine_select() callback, plus the firmware has to be fetched from
the ChromeOS rootfs.

It might make sense to have SOF disabled for now. Removing the adsp
reference and the overriding dai-link entry from the sound node
should do the trick.
