The predefined NAND headers take too much spaces in the mtk_image.c. Moving them into a new file can significantly improve the readability of both mtk_image.c and the new mtk_nand_headers.c. This is a preparation for adding more NAND headers. Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Daniel Golle <daniel@makrotopia.org> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
