mdsal-binding-dom-codec is currently deriving its generated classes from generated interfaces. in AOT world this means we end up with a module conflict: public codegen classes are in the same package as related codec classes.
Allocate a Java package hierarchy to host the codecs, so that YANG-inferred names map to a codegen mapping (as they do now) and codec classes map to a separate hierarchy.
This boils down to eliminating CodecClassLoader.generateClass()'s 'suffix argument – the classes instead use a prefix different to BindingMapping.PACKAGE_PREFIX ("org.opendaylight.yang.gen.v1"), for example "org.opendaylight.yang.rt.v1" .
