ASoC: Updates for v6.17

There's a few new drivers here and quite a lot of cleanup work from
Morimoto-san but generally this has been quite a quiet release,
resulting in a fairly small diffstat.  Highlights include:

 - Refactoring of the Kconfig menus to be hopefully more consistant and
   easier to navigate.
 - Refactoring of the DAPM code, mainly hiding functionality that
   doesn't need to be exposed to drivers.
 - Removal of the unused upstream weak paths DAPM functionality.
 - Further work on the generic handling for SoundWire SDCA devices.
 - Cleanups of our usage of the PM autosuspend functions, this pulls in
   some PM core changes on a shared tag.
 - Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5,
   various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI TAS5753.
