arm64: dts: qcom: x1e80100-crd: Enable external DisplayPort support

Browse Source 
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.
