Add child node 'port' to allow connect to usb controller to do role-switch
if id pin of ptn5150 have not connected to chip's usb ID function pin.

Fix below warning:
arch/arm64/boot/dts/freescale/imx8mn-var-som-symphony.dtb: typec@3d: 'port' does not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/extcon/extcon-ptn5150.yaml
