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]+'

PTN5150 is a small thin low power CC logic chip supporting the USB Type-C
|
|
connector application with CC control logic detection and indication
|
|
functions. It is interfaced to the host controller using an I2C interface.
