arm: dts: odroidxu3: Remove extcon node for a host-only USB 3.0 port
The host-only USB 3.0 port on odroid-xu3 doesn't provide connection
detection through GPIO, but extcon node is configured for this port.
This unnecessary extcon node just represents wrong state for USB
connection. Thus, this patch removes extcon node for a host-only USB
port and configures USB controller in odroid-xu3 specific device tree.
