I like the direction here. Even as the version checks diversify, we
manage to simplify and reduce the macros.

I think we're going to have to queueu this via a topic branch, and merge
that to both drm-intel-next and drm-intel-gt-next. The next time the
branches can sync up is just too far away at this point, and the
conflicts may be really nasty to solve later.

That does mean having to solve the conflict with 70bfb30743d5
("drm/i915/display: Eliminate IS_GEN9_{BC,LP}") which is in din but not
dign. The topic branch would be based on:

$ git merge-base drm-intel/drm-intel-next drm-intel/drm-intel-gt-next
9c0fed84d5750e1eea6c664e073ffa2534a17743

There are two (crappy?) ideas to make that easier. 1) revert
70bfb30743d5 from din and add it to the topic branch instead, 2) don't
revert it but cherry-pick it to the topic branch also.

Cc: Joonas and Daniel for their input on this as well.


BR,
Jani.
