scripts/dts: Never ignore properties in generate_node_defines()
scripts/dts: Never ignore properties in generate_node_defines()

If a binding specifies 'generate: define' for 'interrupt-names' (like
some bindings do), then that ought to generate #defines for it, but the
scripts/dts code currently hardcodes 'interrupt-names' to be ignored
(along with some other properties).

Maybe the 'generate: define' in those bindings is a mistake, but the
code still ought to respect it. That also gets rid of some mystery code.
