    b44: Disable device on shutdown
    
    Disable the SSB core on device shutdown.
    This has two advantages:
    1) A clean device shutdown is always desired here, because we disable
      the device's global crystal in the next statement.
    2) This fixes a bug where the device will come up with the enable-bit
      set on the next initialization (without a reboot inbetween).
      This causes breakage on the second initialization due to code that
      checks this bit (ssb_device_is_enabled() checks).
