sound fixes for 5.8-rc1 

Here are last-minute fixes gathered before merge window close;
 a few fixes are for the core while the rest majority are driver
 fixes.
 
 * PCM locking annotation fixes and the possible self-lock fix
 * ASoC DPCM regression fixes with multi-CPU DAI
 * A fix for inconsistent resume from system-PM on USB-audio
 * Improved runtime-PM handling with multiple USB interfaces
 * Quirks for HD-audio and USB-audio
 * Hardened firmware handling in max98390 codec
 * A couple of fixes for meson
