    mediatek: expand kernel size to 6MiB for WSR-2533DHP2
    
    Expand kernel partition size on WSR-2533DHP2 for the kernel larger than
    4 MiB.
    To prevent upgrading from old firmware before this commit, bump the
    compat version to 1.1 and add a message for forced sysupgrade using
    factory-uboot.bin image.
