The X Elite CRD provides external DisplayPort on all 3 USB Type-C ports.
Each one of this ports is connected to a dedicated DisplayPort
controller.
Due to support missing in the USB/DisplayPort combo PHY driver,
the external DisplayPort is limited to 2 lanes.
So enable all 3 remaining DisplayPort controllers and limit their data
lanes number to 2.
