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.
