The Rockchip I2S controller 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 allowed:
rk3399-rockpro64.dtb: i2s@ff890000: Unevaluated properties are not allowed ('port' was unexpected)
Fix the issue by documenting the missing property.
