sound fixes for 5.3-rc1

A collection of small fixes.
 
 - The optimization of PM resume with HD-audio HDMI codecs, which
   eventually work around weird issues
 - A correction of Intel Icelake HDMI audio code
 - Quirks for Dell machines with Realtek HD-audio codecs
 - The fix for too long sequencer write stall that was spotted by
   syzkaller
 - A few trivial cleanups reported by coccinelle
