    scripts: linksys-image: add NAND devices
    
    The larger switches of the Linksys LGS series (e.g. LGS352C) make
    use of NAND. So the vendor firmware uses other commands to upload
    an image through the WebUI.
    
    Add the required scripts. With this we can upload an image to all
    devices of that series. Independant of NOR or NAND.
