colibri_t20: fix usb operation and controller order
Without this patch the following error will be shown:
Colibri T20 # usb start
starting USB...
No controllers found
This patch fixes USB operation and also the controller order as the
CI UDC driver may only be instantiated on the first aka OTG port.
