[PATCH] USB: EHCI updates (4/4) driver model wakeup flags

Browse Source 
This teaches the EHCI driver to use the new driver model wakeup flags,
replacing the similar ones in the HCD glue.  It also adds a workaround
for the current glitch whereby PCI init doesn't init the wakeup flags
from the PCI PM capabilities.  (EHCI controllers don't worry about
legacy mode; the PCI PM capability would always do the job.)
