    lantiq: fix building AVM/EVA sysupgrade images on NOR devices
    
    Device/AVM unconditionally inherits Device/NAND, which changes the
    sysupgrade image to sysupgrade-tar (instead of a "raw" sysupgrade image
    as used in the Device/Default template).
    This moves the Device/NAND call to the FRITZ3370 device definition, as
    this is the only AVM/EVA device that uses NAND.
    Additionally we have to define the IMAGE_SIZE for the AVM/EVA NOR
    devices to ensure that the images are not discarded.
