[PATCH v6 10/12] usb: doc: dt-binding: Add otg-controller property

[Roger Quadros]

The otg-controller property is used to link the host/gadget
controllers to the otg controller. otg-controller property must
contain the phandle of the otg controller.

The otg core uses this property to tie the host/gadget
controllres to the correct otg controller.
