NAND DRIVER: rk3368 support nand.

    using __dma_map_area and virt_to_phys instead of rknand_dma_map_single
 and rknand_dma_unmap_single.
    dma_map_single need dev config dma ops struct and config dma_mask.
NAND flash driver has not this config and got the incorrect phy addr return by
dma_map_single.
