This patch adds an optional parameter "dr_mode" to the dwc3 core device node.
In the case the compile flag for the DWC3 controller is set to
"USB_DWC3_DUAL_ROLE" a device tree could restrain to either functionality of
host or gadget. In the case the device tree does not use this optional flag or
specifies it superfluously to "drd" the functionality will be that
of a dual role device.
