At present U-Boot has a header file called lz4.h for its own use. If the host has its own lz4 header file installed (e.g. from the 'liblz4-dev' package) then host builds will use that instead. Move the U-Boot file into its own directory, as is done with various other headers with the same problem. Signed-off-by: Simon Glass <sjg@chromium.org>
