[RFC PATCH 1/2] ASoC: codecs: wcd937x: add missing LO Switch control

[Alexey Klimov <alexey.klimov@xxxxxxxxxx>]

The wcd937x supports also AUX input but the control that sets correct
soundwire port for this is missing. This control is required for audio
playback, for instance, on qrb4210 RB2 board as well as on other
SoCs.
