dt-bindings: display: samsung,s6d7aa0: Document port

This MIPI-DSI LCD panel must be connected to something, thus add missing
port property, already used in DTS.  Reported by dtbs_check:

  qcom/msm8916-samsung-gt58.dtb: panel@0 (samsung,lsl080al03): 'port' does not match any of the regexes: '^pinctrl-[0-9]+$'
