Subject: [PATCH 1/6] ata: SATA_MV should depend on HAS_DMA

If NO_DMA=y:

    ERROR: "dma_pool_alloc" [drivers/ata/sata_mv.ko] undefined!
    ERROR: "dmam_pool_create" [drivers/ata/sata_mv.ko] undefined!
    ERROR: "dma_pool_free" [drivers/ata/sata_mv.ko] undefined!

Add a dependency on HAS_DMA to fix this.
