ASoC: Fixes for v3.18

As well as the usual driver fixes there's a few other things here:

One is a fix for a race in DPCM which is unfortuantely a rather large
diffstat, this is the result of growing usage of the mainline code and
hence more detailed testing so I'm relatively happy.

The other is a fix for non-DT machine driver matching following some of
the componentization work which is much more focused.

Both have had a while to cook in -next.
