[PATCH] UHCI: Work around old Intel bug

Some old Intel UHCI controllers have a bug that has shown up in a few
systems (the PIIX3 "Neptune" chip set).  Until now there has not been
any simple way to work around the bug, but the lastest changes in
uhci-hcd have made it easy.  This patch (as684) adds the work-around.
