v4 Updates:
 - Removes already applied patch from v2 of this patchset.
 - Adds small patch to parse Feature Unit number of channels.
 - Rebased onto latest linux-next tag as today.

Now that the UAC3 patch [1] has made it to linux-next I have some extra
features to make a UAC3 devices fully work in Linux. Including Jack 
insertion control that I have put on top of this other patch [2] for 
UAC2. Also adding support for the UAC3 Mixer Unit which is most likely
to appear in most headset type devices.

UAC3 devices also require to have a Basic Audio Device (BADD) in a separate 
config for which both Ruslan Bilovol and myself have submited different 
approaches[3][4]. After an ongoing discussion between Ruslan and myself
we have decided that the patch from Ruslan[3] implements a simpler and
yet more robust BADD driver.

All this features are tested with an actual UAC3 device that is still in
development. For this patch series, only the legacy config (#1. UAC1/UAC2)
and the UAC3 config have been tested. The BADD config will come in
a different patch from Ruslan.
