metag: Provide dma_get_sgtable()
metag/allmodconfig: 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_get_sgtable() is provided in <asm-generic/dma-mapping-common.h>. Metag does not use dma_map_ops yet, hence it should implement it as an inline stub using dma_common_get_sgtable().
