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
