If the following environment, the first argument of DMA API should
be set to a DMAC's device structure, not a udc controller's one.
- A udc controller needs an external DMAC device (like a DMA Engine).
- The external DMAC enables IOMMU.
So, this patch add usb_gadget_{un}map_request_by_dev() API to set
a DMAC's device structure by a udc controller driver.
