Ok, it seems there's a rough consensus of s/IS_GEN/IS_GEN_RANGE/ an then
bring the patches that make sense here. There was a recent patch from Rodrigo
doing that. I'll include it in next version.

By manually inspecting the result of ``git grep -ne "IS_GEN(.*" -- drivers/gpu/drm/i915/``
I didn't find any. The only thing I found was a missed case for gen3 || gen2
that was not covered by the spatch.

only cases of <=, <, >=, >.
