[PATCH] lz4: Use a private header for U-Boot

[Simon Glass <sjg@chromium.org>]

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.
