ASoC: Fixes for v6.9
This is much larger than is ideal, partly due to your holiday but also
due to several vendors having come in with relatively large fixes at
similar times. It's all driver specific stuff.
The meson fixes from Jerome fix some rare timing issues with blocking
operations happening in triggers, plus the continuous clock support
which fixes clocking for some platforms. The SOF series from Peter
builds to the fix to avoid spurious resets of ChainDMA which triggered
errors in cleanup paths with both PulseAudio and PipeWire, and there's
also some simple new debugfs files from Pierre which make support a lot
eaiser.
