mtd: nand: MTD_NAND_ECC_REALTEK should depend on HAS_DMA 



If CONFIG_NO_DMA=y:

    ERROR: modpost: "dma_free_pages" [drivers/mtd/nand/ecc-realtek.ko] undefined!
    ERROR: modpost: "dma_alloc_pages" [drivers/mtd/nand/ecc-realtek.ko] undefined!

The driver cannot function without DMA, hence fix this by adding a
dependency on HAS_DMA.
