Geert Uytterhoeven afbe21d8b3 blackfin: Provide dma_mmap_coherent() and dma_get_sgtable()
blackfin/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>.

Blackfin does not use dma_map_ops, hence it should implement them as inline
stubs using dma_common_mmap() and dma_common_get_sgtable().
