ASoC: Realtek/Maxim SoundWire codecs: disable pm_runtime on remove

When binding/unbinding codec drivers, the following warnings are
thrown:

[ 107.266879] rt715-sdca sdw:3:025d:0714:01: Unbalanced pm_runtime_enable!
[  306.879700] rt711-sdca sdw:0:025d:0711:01: Unbalanced pm_runtime_enable!

Add a remove callback for all Realtek/Maxim SoundWire codecs and remove this
warning.
