    ltq-vdsl-mei: disable optimized firmware download
    
    With ltq-vdsl-mei 1.5.17.6 an optimized firmware download was added and
    enabled by default. As soon as the optimized firmware download is
    enabled, a watchdog based reboot is trigger between 24h to 48h of
    uptime if the board isn't connected to a xdsl line.
