OHCI: add auto-stop support
This patch (as790b) adds "autostop" support to ohci-hcd: the driver will automatically stop the host controller when no devices have been connected for at least one second. This feature is useful when the USB autosuspend facility isn't available, such as when CONFIG_USB_SUSPEND hasn't been set.
