ASoC: Fixes for v4.13

Quite a few fixes here that have been sent since the merge window, the
biggest one is the fix from Tony for some confusion with the device
property API which was causing issues with the of-graph card.  This is
fixed with some changes in the graph API itself as it seemed very likely
to be error prone.
