usb: dwc2: disable erroneous overcurrent condition

For the case where an external VBUS is used, we should enable the external
VBUS comparator in the driver. This would prevent an unnecessary overcurrent
error which would then disable the host port.

The overcurrent condition was happening on the SoCFPGA Cyclone5 devkit, thus
USB was not working on the devkit. This patch fixes that problem.
