ASoC: Fixes for v4.8

A clutch of fixes for v4.8.  These are mainly driver specific, the most
notable ones being those for OMAP which fix a series of issues that
broke boot on some platforms there when deferred probe kicked in.
There's also one core fix for an issue when unbinding a card which for
some reason had managed to not manifest until recently.
