Subject: [PATCH 1/3] [media] v4l: xilinx: VIDEO_XILINX should depend on HAS_DMA

If NO_DMA=y:

    warning: (VIDEO_XILINX && VIDEO_DM365_VPFE && VIDEO_DT3155 && VIDEO_OMAP4) selects VIDEOBUF2_DMA_CONTIG which has unmet direct dependencies (MEDIA_SUPPORT && HAS_DMA)

    media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_mmap’:
    media/v4l2-core/videobuf2-dma-contig.c:207: error: implicit declaration of function ‘dma_mmap_coherent’
    media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_get_base_sgt’:
    media/v4l2-core/videobuf2-dma-contig.c:390: error: implicit declaration of function ‘dma_get_sgtable’

VIDEO_XILINX selects VIDEOBUF2_DMA_CONTIG, which bypasses its dependency
on HAS_DMA.  Make VIDEO_XILINX depend on HAS_DMA to fix this.
