    ramips: add encrypted SGE factory image for D-Link devices
    
    creates SGE encrypted factory images
    to use via the D-Link web interface
    rename the old factory unencrypted images to recovery
    for use in the recovery console when recovery is needed
    
    adjusted to not touch unrelated devices
