frv: Provide dummy dma_mmap_coherent() and dma_get_sgtable()
frv/allmodconfig: drivers/media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_mmap’: drivers/media/v4l2-core/videobuf2-dma-contig.c:204: error: implicit declaration of function ‘dma_mmap_coherent’ drivers/media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_get_base_sgt’: drivers/media/v4l2-core/videobuf2-dma-contig.c:387: error: implicit declaration of function ‘dma_get_sgtable’ For architectures using dma_map_ops, dma_mmap_coherent() and dma_get_sgtable() are provided in <asm-generic/dma-mapping-common.h>. Frv does not use dma_map_ops, hence it should implement them itself. For now, use dummy implementations that just return -EINVAL, until the API has been finalized.
