Do we really need/want a combined/long macro like this and not split it
out to something like a more readable IS_GFX_IPVER && IS_<...>_STEP?
Adding Jani since we were discussing this direction over the past few weeks.
Hm.. macro trickery for stepping ranges to make it more compact? Like
making the STEP_ prefix be prepended by the macro. Don't know..
