Subject: [PATCH 1/3] ASoC: dt-bindings: wcd93xx: add bindings for audio switch controlling hp

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>

On some platforms to minimise pop and click during switching between
CTIA and OMTP headset an additional HiFi Switch is used. Most common
case is that this switch is switched on by default, but on some
platforms this needs a regulator enable.

This patch adds required bindings to add such regulator.
