ASoC: Fixes for v3.14

Browse Source 
A somewhat large set of fixes here due to the identification of some
 systematic problems with hard to use APIs in the subsystem.  Takashi did
 a lot of work to address the enumeration API which uncovered a number of
 off by one bugs caused by confusing APIs while Charles addressed issues
 in the locking around DAPM.
