Reflect tables' layout by grouping indices into enums. Pack & unify all enums into union ddi_vswing_preemph_index. Naming of the data structures is far from perfect and should be a subject to renaming. Capture Vswing / Preemphasis Override tables' layout from MTL onward. Add a placeholder for ICL+.
