mb/intel/coffeelake_rvp: Stop using headers for HDA verbs

One of the variants lacks an hda_verb.h, and hda_verb.c can't be built.
Follow-up changes will make mainboard hda_verb.c files always get built
through AZALIA_PLUGIN_SUPPORT, and breaks building this contraption.

Turn the headers into standalone compilation units to prevent this
issue. Since they contain definitions, including them from multiple
compilation units wasn't a good idea anyway.
