usb: gadget: R8A66597 peripheral controller support. 



While in-tree support for the R8A66597 host side has been supported for
some time, the peripheral side has so far been unsupported. This adds a
new USB gadget driver which bridges the gap and finally wires up the
peripheral side as well.

	   R8A66597 is a discrete USB host and peripheral controller chip that

	   supports both full and high speed USB 2.0 data transfers.

	   It has nine configurable endpoints, and endpoint zero.
