This patchset enable the hdmi audio loopback on the vim3 and vim3l.
I found a few whitespace errors while doing it. This is sent along to
avoid annoying conflicts.

Enable audio capture frontends and a tdm decoder.
This makes it possible to loopback the audio played on the hdmi codec,
which is the only output interface at the moment.
Of course, one TODDR device would be enough to do that but since
the 3 FRDDRs are enabled on the playback side, let's do the same on the
capture side.

Oops this is wrong

And this correct for the vim3 but not the vim3l ...
Please don't take this patch. Patch 1 can still be applied though.
