Sarah Sharp 8a96c05228 USB: xhci: Scatter gather list support for bulk transfers. 
Add support for bulk URBs that pass scatter gather lists to xHCI.  This allows
xHCI to more efficiently enqueue these transfers, and allows the host
controller to take advantage of USB 3.0 "bursts" for bulk endpoints.

Use requested length to calculate the number of TRBs needed for a scatter gather
list transfer, instead of using the number of sglist entries.  The application
can pass down a scatter gather list that is bigger than it needs for the
requested transfer.

Scatter gather entries can cross 64KB boundaries, so be careful to setup TRBs
such that no buffer crosses a 64KB boundary.
