arm64: dts: qcom: x1e80100-dell-xps13-9345: Enable external DP support 



Particular laptops comes with two USB Type-C ports, both supporting DP
alt mode. Enable output on both of them. Explicitly list supported
frequencies including HBR3/8.1Gbps for all external DisplayPort(s).

Due to support missing in the USB/DisplayPort combo PHY driver,
the external DisplayPort is limited to 2 lanes.
