ASoC: Updates for v5.10

Not a huge amount going on in the core for ASoC this time but quite a
lot of driver activity, especially for the Intel platforms:

 - Replacement of the DSP driver for some older x86 systems with a new
   one which was written with closer reference to the DSP firmware so
   should hopefully be more robust and maintainable.
 - A big batch of static checker and other fixes for the rest of the x86
   DSP drivers.
 - Cleanup of the error unwinding code from Morimoto-san, hopefully
   making it more robust.
 - Helpers for parsing auxiluary devices from the device tree from
   Stephan Gerhold.
 - New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359
   Microchip S/PDIF TX and RX controllers, Realtek RT1015P, and Texas
   Instruments J721E, TAS2110, TAS2564 and TAS2764
