    lantiq: set maximum kernel size for P2812HNUF3
    
    The board has 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.
