uhci: Enable "depth" tree traversal for bulk transfers

Set the "depth" flag on bulk transactions.  Since SeaBIOS doesn't use
bandwidth reclamation, without the depth flag the uhci controller will
only transfer one bulk packet per 1 ms frame.  This results in a
maximum of 64 bytes per millisecond, which severely limits the
transfer rate.
