Handling of device tree overlays changed due to introduction of loading and executing an external boot script.
As the boot script can be used for all PHYTEC products (using U-Boot) make a generic include file for overlay handling.
The new file is mostly a copy of the existing imx8 one, but does not contain any product specific info (examples include a specific expansion board, though).
This PR introduces a generic dt-overlays file, that may be included by any product family.
In addition the imx8mp includes this newly generated file as it is the only product making use of the U-Boot standard boot bootflow.
