Ricardo Ribalda 2230124759 [media] videobuf2-dma-sg: Replace vb2_dma_sg_desc with sg_table
Replace the private struct vb2_dma_sg_desc with the struct sg_table so
we can benefit from all the helping functions in lib/scatterlist.c for
things like allocating the sg or compacting the descriptor.
marvel-ccic and solo6x10 drivers, that use this API have been updated.
