Blackfin: easylogo: add lzma logos
The bf527-ezkit boards are getting too big to fit into their reserved flash space, so we need to use a lzma compressed logo. Since the video driver code is very similar, add lzma compressed support to all of the Blackfin video drivers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
