sound fixes for 3.14-rc7

A few fixes for ASoC (N810 DT init fix, DPCM error path fix and
a couple of MFD init fixes), and a fix for a Lenovo laptop.
All small and trivial fixes, suitable for rc7.

ASoC: Fixes for v3.14

A few things here:
 - Avoid memory leaks in error cases with DPCM, this code has never been
   that well tested in mainline due to the lack of mainline drivers but
   we now have one queued for the merge window!
 - Fix the N810 audio driver to load when booted with DT since the
   platform was converted to DT during the merge window.
 - Fixes for initialisation of some MFD drivers that are probably unused
   in mainline
