Add support for direct mapping through mtdconcat, if possible, by attaching the
samebacking_dev_info structure to the master.
It has some restrictions:
(1) It won't permit direct mapping of concatenated devices that have differing
BDIs.
(2) It doesn't support maps that span the 'gap' between devices, although it
possibly could if the devices spanned across return compatible
(ie. contiguous) addresses from their get_unmapped_area() ops.
