ASoC: More changes for v5.1

Another batch of changes for ASoC, no big core changes - it's mainly
small fixes and improvements for individual drivers.

 - A big refresh and cleanup of the Samsung drivers, fixing a number of
   issues which allow the driver to be used with a wider range of
   userspaces.
 - Fixes for the Intel drivers to make them more standard so less likely
   to get bitten by core issues.
 - New driver for Cirrus Logic CS35L26.
