[PATCH 3/3] ASoC: simple-card: Read pin switches conf from devicetree

[Paul Cercueil]

When the routing path between a widget (e.g. "Speaker") and the codec
goes through an external amplifier, having a pin switch for this widget
allows the amplifier to be disabled when the widget is not to be used
(e.g. when using headphones).
