The build of videobuf2-dma-contig.c depends on HAS_DMA and it is
correctly mentioned in the Kconfig but the symbol VIDEO_STI_BDISP also

Even though the issue now manifests itself on m32r, the problem is wider
than that: dma_get_cache_alignment() is only defined if CONFIG_HAS_DMA is
I wonder if using videobuf2-dma-contig makes any sense if HAS_DMA is
disabled, so perhaps it'd be possible to make it depend on HAS_DMA.
