ASoC: Fixes for v6.12

The biggest set of changes here is Hans' fixes and quirks for various
 Baytrail based platforms with RT5640 CODECs, and there's one core fix
 for a missed length assignment for __counted_by() checking.  Otherwise
 it's small device specific fixes, several of them in the DT bindings.
