The update-u-boot-script implementation uses a runtime loop to iterate
over the content each individual overlay entry. This is required because
the entry might contain an u-boot variable, containing multiple overlays
itself.

To avoid incorrect code cleanups like in 680ad26, we add a comment about
this special handling.
