arm64: dts: qcom: x1e80100-qcp: Enable external DP support
Now that the FSUSB42 USB switches are described, enable support for DP on
the three USB-C ports of the X1E80100 QCP. It supports up to 4 lanes, but
for now we need to limit this to 2 lanes due to limitations in the USB/DP
combo PHY driver. The same limitation also exists on other boards upstream.
