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.
