[PATCH master] treewide: add missing device tree artifact cleanup where needed

[Ahmad Fatoum <ahmad@a3f.at>]

The DTs in arch/$ARCH/dts are all cleaned up when invoking the make
target, but we have a few DTs outside these directories.

Clean those up as well and add a clean line for the overlay too.
