ASoC: Updates for v6.4
The bulk of the commits here are for the conversion of drivers to use
void remove callbacks but there's a reasonable amount of other stuff
going on, the pace of development with the SOF code continues to be high
and there's a bunch of new drivers too:
- More core cleanups from Morimto-san.
- Update drivers to have remove() callbacks returning void, mostly
mechanical with some substantial changes.
- Continued feature and simplification work on SOF, including addition
of a no-DSP mode for bringup, HDA MLink and extensions to the IPC4
protocol.
- Hibernation support for CS35L45.
- More DT binding conversions.
- Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363,
nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas R-Car
Gen4, Rockchip RK3588 and TI TAS5733.
