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().
