Last minute ASoC updates for 3.4

Browse Source 
There's a couple of small features here that were added late on but have
 been in -next in my tree and some bug fixes.  The wm_hubs stuff is
 actually bug fixes - the stuff that's currently in 3.4 is a half way
 house between the two solutions that the latest change allows the
 machine to select between.
