ASoC: mt8192: Fixes from initial glance at kselftest

Merge series from Mark Brown <broonie@kernel.org>:

This is a collection of fixes I came up after glancing through an
initial test run with the Spherion Chromebook on KernelCI.  There are
more issues flagged, this is just what I fixed thus far - the volume
controls on the MT6359 have issues for example, and a lot of controls
aren't marked as Switches like they should be.
