USB: Export if an interface driver supports autosuspend.
Create a new sysfs file per interface named supports_autosuspend. This file returns true if an interface driver's .supports_autosuspend flag is set. It also returns true if the interface is unclaimed (since the USB core will autosuspend a device if an interface is not claimed). This new sysfs file will be useful for user space scripts to test whether a USB device correctly auto-suspends.
