ASoC: Updates for v5.8
This has been another very active release with a bunch of new drivers,
lots of fixes everywhere and continued core improvements from
Morimoto-san:
- Lots of core cleanups and refactorings from Morimoto-san, factoring
out common operations and making the card abstraction more solid.
- Continued work on cleaning up and improving the Intel drivers, along
with some new platform support for them.
- Fixes to make the Marvell SSPA driver work upstream.
- Support for AMD Renoir ACP, Dialog DA7212, Freescale EASRC and
i.MX8M, Intel Elkhard Lake, Maxim MAX98390, Nuvoton NAU8812 and
NAU8814 and Realtek RT1016.
