The need for CONFIG_USB_AU1200OTG is board-specific, and doesn't belong in Kconfig. Also, the au1200_otg code should live with platform code ... plan for it to become "real OTG support" (at least for cable based role switching), and then it becomes clear that it does not belong in the drivers/usb host or gadget directories (since it affects both).
