ASoC: Updates for v6.19

This is a very large set of updates, as well as some more extensive
cleanup work from Morimto-san we've also added a generic SCDA class
driver for SoundWire devices enabling us to support many chips with
no custom code.  There's also a batch of new drivers added for both
SoCs and CODECs.

 - Added a SoundWire SCDA generic class driver, pulling in a little
   regmap work to support it.
 - A *lot* of cleaup and API improvement work from Morimoto-san.
 - Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm
   drivers.
 - Support for Allwinner A523, Mediatek MT8189, Qualcomm QCM2290,
   QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806,
   TAS5815, TAS5828 and TAS5830.

This also pulls in some gpiolib changes supporting shared GPIOs in the
core there so we can convert some of the ASoC drivers open coding
handling of that to the core functionality.
