[U-Boot] [PATCH v1 4/5] colibri_t20: fix usb operation and controller order

[Marcel Ziswiler]

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.
