Subject: [PATCH] ASoC: dt-bindings: everest,es8328: Document audio graph
 port

The ES8328/ES8388 audio codec is currently used in conjunction with
audio-graph-card to provide an endpoint for binding with the other side
of the audio link.

This is achieved via the 'port' property, which is not supported by the
binding:

  rk3588s-indiedroid-nova.dtb: audio-codec@11: 'port' does not match any of the regexes: 'pinctrl-[0-9]+'
    from schema $id: http://devicetree.org/schemas/sound/everest,es8328.yaml#

Document the missing property.
