[PATCH] device-tree: Move dt-overlay.c to common/device-tree/

[Michal Orzel <michal.orzel@xxxxxxx>]

The code is DT specific and as such should be placed under common
directory for DT related files. Update MAINTAINERS file accordingly
and drop the line with a path from a top-level comment in dt-overlay.c.
It serves no purpose and requires being updated on every code movement.
