[PATCH] [media] v4l: VIDEO_SH_VOU should depend on HAS_DMA

[Geert Uytterhoeven]

If NO_DMA=y:

    warning: (VIDEO_DM6446_CCDC && VIDEO_DM355_CCDC && VIDEO_DM365_ISIF && VIDEO_OMAP2_VOUT && VIDEO_SH_VOU && VIDEO_VIU && VIDEO_TIMBERDALE && VIDEO_MX1 && VIDEO_OMAP1) selects VIDEOBUF_DMA_CONTIG which has unmet direct dependencies (MEDIA_SUPPORT && HAS_DMA)

VIDEO_SH_VOU selects VIDEOBUF_DMA_CONTIG, which bypasses its dependency on
HAS_DMA.  Make VIDEO_SH_VOU depend on HAS_DMA to fix this.
