Chuanhong Guo 75f19deb3a ramips: define image recipe for uncompressed uimage with loader
Some devices have bootloaders with broken lzma code resulting in failed
decompression or corrupted kernel code.
This image recipe allows to sacrifice 5KB for OpenWrt LZMA loader and
take over the task of decompress kernel.
