The build process that you describe is not in our documentation.

By which defconfig is $(src)/dsdt.asl consumed? Where does it come from? 
Please, provide a reproducible example.

Would you be able to provide a documentation patch explaining how to use 
a user provided dsdt.asl file?

Best regards

Heinrich
