Is there is reason to include device nodes in dts file for usb devices that are attached to a usb host? What additional information would such nodes include apart from the device information obtained during enumeration?

There are cases where soldered down USB devices on the mainboard will have additional connections that cannot be discovered by the driver. GPIOs for instance, or an Ethernet device that needs to be assigned a MAC address.
