This patch add the core driver for the c67x00 USB OTG controller. The core driver is responsible for the platform bus binding and creating either USB HCD or USB Gadget instances for each of the serial interface engines on the chip. This driver does not directly implement the HCD or gadget behaviours; it just controls access to the chip.
