nand_ecclayout is present in mtd.h at Linux.
Move this structure to mtd.h to comply with Linux.
Also, increase the ecc placement locations to 640 to suport device having
writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone
up to 640 bytes and consequently the maximum ecc placement locations have
also gone up to 640.
