[U-Boot] [PATCH] mtd: nand: denali: correct buffer alignment for DMA transfer

The NAND framework makes sure to pass in the buffer with at least chip->buf_align alignment. Currently, the Denali NAND driver only requests 16 byte alignment. This causes unaligned cache operations for the DMA transfer. [Error Example] => nand read 8110 0 1000 NAND read: device 0 offset 0
