ASoC: Fixes for v5.16

A relatively large collection of updates, the size is increased quite a
bit by there being some repetitive changes for similar issues that occur
multiple times with both notifying control value changes and runtime PM.

The Rockchip update looks at first glance like a cleanup but fixes
instantiation of the hardware on some systems.
