Well patch 13/13 of this set relies on 5/5 from the previous set which is
only in Mark's ASoC tree and not in the MFD tree, so splitting things over MFD + ASoC
again makes the most sense here too.

The alternative is Mark doing a PR from ASoC to MFD to get 5/5 from the previous set
in MFD first, which seems less then ideal.
