But you haven't tested / added support for device mode yet, so please
remove those references.

We don't need an extra test of CONFIG_USB_AM335X around this, just
CONFIG_MUSB_HCD and later MUSB_UCD.

You didn't add nor test keyboard so please remove these bits until
U-Boot support is at the point where you could use one of these boards
over a display rather than USB console :)  Thanks.
