[PATCH v2 1/1] arm64: dts: Add usbphynop and usbotg pinctrl for S32G platforms

[Khristine Andreea Barbulescu]

Add the usbphynop node and the usbotg pinctrl
support for the S32G2 and S32G3 SoCs.

This enables the USB controller to reference the
generic PHY and use the required pinmux for USB OTG ops.
