ASoC: audio-graph-card: update bindings for amplifier support

Browse source

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.
