ASoC: Final updates for v3.20

A few more updates for v3.20 that have accumilated over the second half
of last week.  One new (relatively simple) driver for the Maxim
max98357a and some other driver specific fixes and enhancements.  I did
apply a few patches that haven't been in -next just now before sending
this, all fixes except for one simple device ID addition patch.
