[PATCH 10/12] caif: CAIF_VIRTIO should depend on HAS_DMA

[Geert Uytterhoeven]

If NO_DMA=y:

drivers/built-in.o: In function `cfv_destroy_genpool':
drivers/net/caif/caif_virtio.c:364: undefined reference to `dma_free_coherent'
drivers/built-in.o: In function `cfv_create_genpool':
drivers/net/caif/caif_virtio.c:397: undefined reference to `dma_alloc_coherent'
