Same here as previous patch. These should be added one platform per
patch, converting the IS_FOO_REVID() macros to
IS_FOO_{GT,DISPLAY}_STEP() and the new stepping info while at it. Look
at the platforms already added. The main point here is being able to
abstract the steppings in intel_step.c so we can use the generic STEP_XY
enums. Having both makes this more complicated.
