util/sconfig: Throw an error if override tree has no devices
If override tree does not have any device, then the chip info
structure in it cannot be associated with the correct device and ends
up being added as a standalone chip info structure without any device
actually using it. This change prevents this condition by throwing an
error during compilation.
