Mark Kettenis ba1efb3d24 usb: xhci: Implement DMA mapping 
An XHCI controller that sits behind an IOMMU needs to map and unmap
its memory buffers to do DMA.  Implement this by inroducing new
xhci_dma_map() and xhci_dma_unmap() helper functions.  The
xhci_dma_map() function replaces the existing xhci_virt_to_bus()
function in the sense that it returns the bus address in the case
of simple address translation in the absence of an IOMMU.  The
xhci_bus_to_virt() function is eliminated by storing the CPU
address of the allocated scratchpad memory in struct xhci_ctrl.
