Subject: [PATCH 1/2] usb: gadget: udc: USB_RENESAS_USB3 should depend on HAS_DMA

If NO_DMA=y:

    ERROR: "usb_gadget_map_request" [drivers/usb/gadget/udc/renesas_usb3.ko] undefined!
    ERROR: "usb_gadget_unmap_request" [drivers/usb/gadget/udc/renesas_usb3.ko] undefined!
    ERROR: "bad_dma_ops" [drivers/usb/gadget/udc/renesas_usb3.ko] undefined!

Add a dependency on HAS_DMA to fix this.
