The "omap_otg" platform device has to be registered in order
to get USB working on the n810.
I currently do this by calling the USB-FS init, which in turn
registers the omap_otg platform device.
The omap_usb_config structure values were copied from n770 code, so
I have no idea whether this is correct or not.
However, with all the patches I just sent (including this one),
I get USB working properly on the n810.
