This is only used by GRAPHICS_VER == 6 and GRAPHICS_VER == 7. All other recent platforms do not depend on this field, so it doesn't make much sense to keep it generic like that. Instead, just do a mapping from engine class to HW ID in the single place that is needed.
v2: use macros with the direct register address instead of calculating from the legacy HW_ID (Matt Roper)
