[PATCH 2/7] dt-bindings: usb: dwc3: Add a gpio-usb-connector example

[Bryan O'Donoghue]

A USB connector should be a child node of the USB controller
connector/usb-connector.txt. This patch adds an example of how to do this
to the dwc3 binding descriptions.

It is necessary to declare a connector as a child-node of a USB controller
for role-switching to work, so this example should be helpful to others
implementing that.
