cmd: bmp: Split bmp commands and functions
To enable splash screen at SPL, need to compile cmd/bmp.c which also includes bmp commands, since SPL doesn't use commands split bmp.c into common/bmp.c which includes all bmp functions and cmd/bmp.c which only contains bmp commands. Add function delclaration for bmp_info in video.h. Signed-off-by: Nikhil M Jain <n-jain1@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>
