[PATCH] USB: wakeup flag updates (2/3) uhci-hcd

This makes UHCI stop using the HCD glue wakeup flags to report whether
the controller can wake the system.  The existing code was wrong anyway;
having a PCI PM capability doesn't imply it reports PME# is supported.

I skimmed Intel's ICH7 datasheet and that basically says the wakeup
signaling gets routed only through ACPI registers.  (On the other hand,
many VIA chips provide the PCI PM capabilities...)  I think that doing
this correctly with UHCI is going to require the ACPI folk to associate
the /proc/acpi/wakeup identifiers (and wakeup enable/disable flags)
with the relevant /sys/devices/pci*/...  devices.
