ASoC: Updates for v6.6

The rest of the updates for v6.6, some of the highlights include:

 - A big API cleanup from Morimoto-san, rationalising the places we put
   functions.
 - Lots of work on the SOF framework, AMD and Intel drivers, including a
   lot of cleanup and new device support.
 - Standardisation of the presentation of jacks from drivers.
 - Provision of some generic sound card DT properties.
 - Conversion oof more drivers to the maple tree register cache.
 - New drivers for AMD Van Gogh, AWInic AW88261, Cirrus Logic cs42l43,
   various Intel platforms, Mediatek MT7986, RealTek RT1017 and StarFive
   JH7110.
