Actually, this does NOT work: I just had a long morning debugging SPL
which no longer started because it picked the non-filtered dtb. The
filtered one ended up in a folder outside of the u-boot sources because
of all those ../ and hard-wiring to dts/upstream.

workarounds to far. They don't converge although I already patched some
core Makefile (overlays are building now).
