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     |
+------+------------------+------------------+---------------+-----------------+
