ASoC: audio-graph-card: add widgets and routing for external amplifier support
It's very common that audio card has a machine level amplifier which is
controlled by GPIO. The patch adds DAPM widgets and routing support
into audio-graph-card driver, and creates an output driver widget with
event to control the amplifier via GPIO.
