Have you checked that this currently works?  The AC97 bus should be
unregistered when the audio device is unregistered.  I have to confess
that I haven't tested this in v2 but it is the intended behaviour - the
AC97 controller is provided by the ASoC drivers so when it is stopped
the link should be unregistered.
