Linus Torvalds d93a8f829f Revert "USB: Work around BIOS bugs by quiescing USB controllers earlier" 
This reverts commit db8be50c43, as per

	http://bugzilla.kernel.org/show_bug.cgi?id=14374
	http://marc.info/?l=linux-kernel&m=125446885705223&w=4

We simply can't do the USB handoff at FIXUP_HEADER time, since it will
often require us to have valid IO mappings etc.  But that in turn
requires a whole different approach, not this trivial one-liner.

Maybe we could teach all the USB quirk handoff handlers to only do the
quirk if the device has all its registers set up (since if it isn't
initialized, it's unlikely to be active), but regardless that will need
a whole lot more code than just saying "let's do it really early".

The proper fix is almost certainly to just leave the legacy IOMMU
mappings active until after all devices have been initialized.
