sh: add r8a66597 usb1 gadget to the se7724 board
Add USB gadget support for port CN26 on the Solution Engine 7724 board. The r8a66597-udc driver is hooked up as a platform device and some registers are configured to enable the USB in gadget mode. The hardware driving the USB port is the on-chip USB1 block in the sh7724 processor configured as USB gadget controller.
