[PATCH v2 3/7] drm/i915: replace IS_GEN<N> with GT_GEN(..., N)

[Lucas De Marchi]

Define GT_GEN() similarly to our GT_GEN_RANGE() and convert users of
IS_GEN<N> to pss the gen as parameter. This prepares for the addition
of display gen checks by renaming the IS_GENx() and using common code
for all the n gens.

The following spatch was used to convert the users of these macros:

expression e;
