[PATCH] USB: ohci uses driver model wakeup flags

This makes OHCI use the driver model wakeup control bits for its root hub
(e.g. disable on amd756, because of chip erratum) and for the controller
itself.  It no longer uses the hcd glue bits with those roles, and depends
on the previous patch making the root hub available earlier.

Note that on most platforms (boot code properly setting the RWC bit) this
gives a partial workaround for the way PCI isn't currently flagging devices
that support PME# signals.  (Because of odd PCI init sequencing on PPC.)
That's because many OHCI controllers support "legacy PCI PM" ... without
involving any PCI PM capability.

USB wakeup from STR, if it works on your system, may still involve
tweaking things by hand in /proc/acpi/wakeup.
