[PATCH] Documentation: sysfs-bus-usb: update power/persist description

[Paul Bolle]

There's no power/persist file for hubs. And CONFIG_USB_PERSIST was
removed in v2.6.26. Update the description of power/persist accordingly.

I don't know anything about USB-Persist. Could Greg and Alan please
check whether the new description does actually match reality?

 Description:
-		If CONFIG_USB_PERSIST is set, then each USB device directory
-		will contain a file named power/persist.  The file holds a
-		boolean value (0 or 1) indicating whether or not the
-		"USB-Persist" facility is enabled for the device.  Since the
-		facility is inherently dangerous, it is disabled by default
-		for all devices except hubs.  For more information, see
-		Documentation/usb/persist.txt.
