ASoC: Fixes for v3.16

A bigger batch of changes than I would like as I didn't send any for a
few weeks without noticing how many had built up.  They are almost all
driver specific though, larger changes are:

 - Fixes to the newly added Baytrail/MAX98090 which look like some QA
   was missed on the microphone detection.
 - Deletion of some erroniously listed audio formats for Haswell.
 - Fix debugfs creation in the core so that we don't try to generate
   multiple directories with the same name, relatively large textually
   but simple to inspect by eye and test.
 - A couple of bugfixes for the rcar driver one of which which involves
   a bit of code motion to move initailisation of some hardware out of
   common paths into device specific ones.
 - Ensure both channels are powered up for mono outputs on Arizona
   devices, involving some simple data tables listing the outputs and a
   loop over them.
 - A couple of fixes to save and restore information on suspended and
   idle Samsung I2S controllers.
