[PATCH 3/5] Fix the bug of writing a yaffs2 image to NAND

The tool mkyaffs2image doesn't know the oob layout of a NAND flash, so it
puts the yaffs2 tags at the offset 0 of oob area. When nandwrite writes the
image into NAND flash, it should put the yaffs2 tags at the right position
according to the NAND oob layout.
