spl: fit: Break out some functions into a common file
Some of the functions within spl_fit will be used for non spl purposes. Instead of duplicating functions simply break the functions to be reused into its own file. Signed-off-by: Franklin S Cooper Jr <fcooper@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Only add the new define to image.h, otherwise we see breakage due to massive include leakage into host tools in some cases] Signed-off-by: Tom Rini <trini@konsulko.com>
