In order to have the usb phy work in gadget mode, override
the default host mode with otg mode.
This allows gadget mode to work w/o any hacks to the dtsi file.

Wouldn't this be the standard case for the first/primary USB on most
8064s? Looks like both the ifc6410 and sd600eval has OTG support on the
micro-usb.
Andy, how about we just change the dtsi instead?

Bjorn
