ASoC: Fixes for v5.5

This is mostly driver specific fixes, plus an error handling fix
in the core.  There is a rather large diffstat for the stm32 SAI
driver, this is a very large but mostly mechanical update which
wraps every register access in the driver to allow a fix to the
locking which avoids circular locks, the active change is much
smaller and more reasonably sized.
