[PATCH v4 2/3] ASoC: dt-bindings: audio-graph-card2: add widgets and hp-det-gpios support

[Laurentiu Mihalcea]

From: Laurentiu Mihalcea <laurentiu.mihalcea@xxxxxxx>

Introduce the 'widgets' property, allowing the creation of widgets from
4 template widgets: Microphone, Line, Headphone, and Speaker. Also
introduce the 'hp-det-gpios' property, which allows using headphone
detection using the specified GPIO.
