mmc: MMC_MTK should depend on HAS_DMA



If NO_DMA=y:

    ERROR: "dma_alloc_coherent" [drivers/mmc/host/mtk-sd.ko] undefined!
    ERROR: "dma_unmap_sg" [drivers/mmc/host/mtk-sd.ko] undefined!
    ERROR: "dma_map_sg" [drivers/mmc/host/mtk-sd.ko] undefined!
    ERROR: "dma_free_coherent" [drivers/mmc/host/mtk-sd.ko] undefined!

Add a dependency on HAS_DMA to fix this.
