ASoC: Updates for v4.16

Browse Source 
With the merge window having been delayed for another week here's
 another batch of updates that came in during that week.  There's a few
 important fixes in here, mainly a fix for I/O on a number of devices
 caused by some of the component rework and a fix for a potential issue
 if more than one component in a link provides compressed operations.
 The I/O fixes are particularly important as the problem causes a power
 regression on a number of OMAP platforms.
