[PATCH v2 4/7] media: vb2-dma-contig: add helper for setting dma max seg size

Add a helper function for device drivers to set DMA's max_seg_size. Setting it to largest possible value lets DMA-mapping API always create contiguous mappings in DMA address space. This is essential for all devices, which use dma-contig videobuf2 memory allocator and shared buffers.
