As described in the documentation, upstream device trees extended by
barebox should take care to cause compile errors, not runtime errors,
when the paths they extend disappear. This way, breakage can be easily
detected when synchronizing the dts/ directory and fixed right then.

Make this process easier by providing a dtbs target that builds all
device trees in arch/$(SRCARCH)/dts/ if available.
