USB: convert to the runtime PM framework
This patch (as1329) converts the USB stack over to the PM core's runtime PM framework. This involves numerous changes throughout usbcore, especially to hub.c and driver.c. Perhaps the most notable change is that CONFIG_USB_SUSPEND now depends on CONFIG_PM_RUNTIME instead of CONFIG_PM. Several fields in the usb_device and usb_interface structures are no longer needed. Some code which used to depend on CONFIG_USB_PM now depends on CONFIG_USB_SUSPEND (requiring some rearrangement of header files). The only visible change in behavior should be that following a system sleep (resume from RAM or resume from hibernation), autosuspended USB devices will be resumed just like everything else. They won't remain suspended. But if they aren't in use then they will naturally autosuspend again in a few seconds.
