ASoC: Updates for v5.6
A pretty big release this time around, a lot of new drivers and both
Morimoto-san and Takashi were doing subsystem wide updates as well:
- Further big refactorings from Morimoto-san simplifying the core
interfaces and moving things to the component level.
- Transition of drivers to managed buffer allocation and removal of
redundant PCM ioctls.
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
and RT1308.
