[PATCH] usbcore PCI glue updates for PM
This updates the PCI glue to address the new and simplified usbcore suspend
semantics, where CONFIG_USB_SUSPEND becomes irrelevant to HCDs because
hcd->hub_suspend() will always be called.
- Removes now-unneeded recursion support
- Go back to ignoring faults reported by the wakeup calls; we expect them
to fail sometimes, and that's just fine.
The PCI HCDs will need simple changes to catch up to this, like being able
to ignore the setting of CONFIG_USB_SUSPEND.
