Add missed byteswap ops for BE machines in block added in rev 1.223.
Call usb_syncmem() against descriptors more strictly.
(not sure if the previous ones were fatal though)
Deal with control transfers better by
        - removing the UHCI_PTR_VF flag for the setup and status stages
          which means they are scheduled less aggressively.  Some devices
          appear to require this (blymn@ has one).  The flag was
          introduced as a performance improvement for bulk transfers.
        - Checking for short reads and making sure the status stage runs
          if they're encountered.
PR/47522 Enumeration of LUFA/Atmel devices on UHCI fails
Thanks to jak@ and blymn@ for testing and mlelstv@ for comments.
