ASoC: audio-graph-card: update bindings for amplifier support
The audio-graph-card should be able to support widgets and routing in
the same way as what simple-audio-card does. The patch adds the
properties into audio-graph-card bindings. Then an optional property
'pa-gpios' for controlling external amplifier, which depends on DAPM
widgets and routing, is added.
