[PATCH] of: move of_get_node_by_reproducible_name() into common code

[Ahmad Fatoum]

The function already has a good generic name and can be useful for board
code or for other drivers seeking to fix up the kernel device tree
according to information within the barebox DT.
Thus move it to a central location.
