arm64: dts: qcom: x1e80100-t14s: Enable external DisplayPort support

Browse source

The Lenovo ThinkPad T14s Gen6 provides external DisplayPort on all
2 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 the first and second DisplayPort controllers and limit their
data lanes number to 2.
