Subject: [PATCH AUTOSEL 5.15 03/28] ASoC: Realtek/Maxim SoundWire codecs: disable pm_runtime on remove

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit ac63716da3070f8cb6baaba3a058a0c7f22aeb5b ]

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.
