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)

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