    ramips: introduce TP-Link v1 header OKLI image recipe
    
    It can be used to workaround the booting stuck issue caused by the
    u-boot LZMA decompression error.
    
    The new kernel image structure:
    +------+------------------+------------------+---------------+-----------------+
    | name | tplink-v1 header | OKLI lzma-loader | uImage header | lzma kernel+dtb |
    +------+------------------+------------------+---------------+-----------------+
    | size |      0x200       |       0xe00      |     0x40      |     dynamic     |
    +------+------------------+------------------+---------------+-----------------+
