[media] Input: TOUCHSCREEN_SUR40 should depend on HAS_DMA

Browse source 
If NO_DMA=y:

    warning: (TOUCHSCREEN_SUR40 && VIDEO_TW68 && VIDEO_CX23885 && VIDEO_CX25821 && VIDEO_CX88 && VIDEO_SAA7134) selects VIDEOBUF2_DMA_SG which has unmet direct dependencies (MEDIA_SUPPORT && HAS_DMA)

    ERROR: "dma_unmap_sg" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined!
    ERROR: "dma_map_sg" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined!
    ERROR: "dma_sync_sg_for_cpu" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined!

TOUCHSCREEN_SUR40 selects VIDEOBUF2_DMA_SG, which bypasses its
dependency on HAS_DMA.  Make TOUCHSCREEN_SUR40 depend on HAS_DMA to fix
this.
