libpayload: Fill gaps in the xHCI driver
Well, it turned out to be more as some gaps ;) but we finally have xHCI running. It's well tested against a QM77 Ivy Bridge board. We have no SuperSpeed support (yet). On Ivy Bridge, SuperSpeed is not advertised and USB 3 devices will just work at HighSpeed. There are still some bit fields in xhci_private.h, so this might need little more work to run on ARM.
