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.
