[PATCH 05/11] ASoC: dt-bindings: rockchip: i2s-tdm: Document audio graph port

[Cristian Ciocaltea]

Document the 'port' property to allow the Rockchip I2S TDM controller to
be used in conjunction with the audio-graph-card.

The property will be used to provide an endpoint for binding to the
other side of the audio link.
