arm64: dts: qcom: x1e80100-crd: Add USB multiport fingerprint reader

Browse Source 
The X1E80100 CRD has a Goodix fingerprint reader connected to the USB
multiport controller on eUSB6. All other ports (including USB super-speed
pins) are unused.

Set it up in the device tree together with the NXP PTN3222 repeater.
