arm64: dts: imx8mp-var-som-symphony: enable USB support

Browse Source 
Enable the USB controllers on the Symphony carrier board.

Add the PTN5150 Type-C controller for USB role switching, enable the USB3
PHYs and controllers, configure the I2C bus used by the Type-C
controller, and set the first USB port in OTG mode and the second port
in host mode.
