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 81000010 0 1000
NAND read: device 0 offset 0x0, size 0x1000
CACHE: Misaligned operation at range [81000010, 81001010]
CACHE: Misaligned operation at range [81000010, 81001010]
CACHE: Misaligned operation at range [81000010, 81001010]
CACHE: Misaligned operation at range [81000010, 81001010]
