In some cases, nand_do_{read,write}_ops is passed with unaligned ops->datbuf. Drivers using DMA will be unhappy about unaligned buffer. The new struct member, buf_align, represents the minimum alignment the driver require for the buffer. If the buffer passed from the upper MTD layer does not have enough alignment, nand_do_*_ops will use bufpoi. Signed-off-by:
