ASoC: SDCA: Handle volatile controls correctly

Browse source

[ Upstream commit 9fad74b79e ]

There are very few volatile controls in SDCA that are exported
as ALSA controls, typically Detected Mode is the only common
one. However, the current code does not resume the device when
these ALSA controls are accessed, which will result in the
read/write failing.

Add a new wrapper specifically for volatile controls that will do
the required pm_runtime operations before accessing the register.
