[PATCH RFC] n810 USB: Initialize USB-FS

[PATCH RFC] n810 USB: Initialize USB-FS

[Michael Buesch]

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.

Is there any news on this one?
If not, I'd suggest merging this in its current form, even if
we're unsure whether it's 100% correct, because it actually
makes the USB work on the n810.

If you merge this, you can add a
