Alan Stern 4fe5354f61 EHCI: fix problem with BIOS handoff 
This patch (as882) fixes a problem with the EHCI BIOS handoff.  On my
machine, the BIOS configures the controller and the handoff fails,
leaving the controller configured.  During resume-from-disk, this
confuses ehci-hcd into thinking that the controller has not been
tampered with.

The problem is fixed by turning off the Configured Flag whenever a
BIOS handoff is attempted, whether it succeeds or not.
