Now that fdtoverlay is part of the kernel build, start using it to test
the unitest overlays we have by applying them statically.

Nice idea.

The file overlay_base.dtb have symbols of its own and we need to apply
overlay.dtb to overlay_base.dtb alone first to make it work, which gives
us intermediate-overlay.dtb file.

Okay? If restructuring things helps we should do that. Frank?

Frank, do we want to do something about it ? Maybe make overlay_base.dts an dtsi
and include it from testcases.dts like the other ones ?

No, because overlay_base.dts is an overlay dt. I think we need an
empty, minimal base.dtb to apply overlay_base.dtbo to.

And then fdtoverlay needs a fix to apply overlays to the root node?
