[PATCH] UHCI: Workaround for broken remote wakeup

This patch adds a workaround for host controllers that don't properly
support remote wakeup.  That includes Intel controllers (on certain badly
designed motherboards) and a recent Genesys Logic controller.  Although
the UHCI driver avoids suspending the Intel-based controllers, this
workaround will handle things about as well.

In the not-too-distant future I will have to revamp most of the root-hub
suspend/resume code in the UHCI driver.  For now, please apply the patch.
