Documentation: sysfs-bus-usb: update power/persist description 



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.
Also remove the line on its default value. It is not entirely correct, as
CONFIG_USB_DEFAULT_PERSIST and the USB_QUIRK_RESET flag influence the
default. It is not needed to understand this file anyhow.

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.

		USB device directories can 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.  For

		hubs this facility is always enabled and their device

		directories will not contain this file.



		For more information, see Documentation/usb/persist.txt.
