[PATCH] [media] media: ti-vpe: add dependency of HAS_DMA

[Sudip Mukherjee]

The build of m32r allmodconfig fails with the error:
 drivers/media/v4l2-core/videobuf2-dma-contig.c:492:28: error: implicit
	declaration of function 'dma_get_cache_alignment'

The build of videobuf2-dma-contig.c depends on HAS_DMA and it is
correctly mentioned in the Kconfig but the symbol VIDEO_TI_CAL also
selects VIDEOBUF2_DMA_CONTIG, so it is trying to compile
videobuf2-dma-contig.c even though HAS_DMA is not defined.

Fixes: 343e89a792a5 ("[media] media: ti-vpe: Add CAL v4l2 camera capture driver")
