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
