You should also make new mixer control sets, with out linein and mic2,
and split out the mixer widget for V3s. Otherwise ALSA is going to
export MIC2 and LineIn playback/capture switches to userspace, which
is going to be confusing to the user. We've never needed this in the
past because all SoCs shared the same set of mixer controls.
