ASoC: Fixes for v5.18

A larger collection of fixes than I'd like, mainly because mixer-test
 is making it's way into the CI systems and turning up issues on a wider
 range of systems.  The most substantial thing though is a revert and an
 alternative fix for a dmaengine issue where the fix caused disruption
 for some other configurations, the core fix is backed out an a driver
 specific thing done instead.
