Uhm... I think that we should either have audio, with DSP, or not have it
at all... the userspace configurations will differ, so we'd end up with
two different confs of which one will get unused and cluttering the ucm2
conf git.

At this point, I think that the most sensible option is to either omit
this commit, or keep audio disabled until the machine_select() callback
gets in...
