    lantiq: set maximum kernel size
    
    These boards have a fixed size kernel partition but do not limit the
    kernel size during image building.
    
    Disable image building for both boards as well, since the kernel of the
    last release as well as master are to big to fit into the 2 MByte kernel
    partition.
