ASoC: Updates for v5.11

There's a lot of changes here but mostly cleanups and driver specific
things, the most user visible change is the support for boot time
selection of Intel DSP firmware which will make it easier for people to
move over to the preferred modern implementations in distros and other
large scale deployments.

This also includes a merge of the new auxillary bus which was done in
anticipation of use by the Intel DSP drivers which didn't quite make it.

 - Lots more cleanups and simplifications from Morimoto-san.
 - Support for some basic DPCM systems in the audio graph card from
   Sameer Pujar.
 - Remove some old pre-DT Freescale drivers for platforms that are now
   DT only.
 - Move selection of which Intel DSP implementation to use to boot time
   rather than requiring it to be selected at build time.
 - Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
   Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek RT715,
   Qualcomm SM8250 and simple GPIO based muxes.
