Although MTL is the only platform right now that uses Xe_LPG IP, this may not always be the case. If a future platform re-uses this graphics IP, the same workarounds should be applied, even if it isn't a "MTL" platform. We were also incorrectly applying Xe_LPG workarounds/tuning to the Xe_LPM+ media IP in one or two places; we should make sure that we don't try to apply graphics workarounds to the media GT and vice versa where they don't belong. A new helper macro GT_GRAPHICS_RANGE() is added to help ensure this is handled properly -- it checks both the graphics version range and that the code isn't operating on a media GT. Note that many of the stepping-based workarounds are still incorrectly checking for a MTL base platform; that will be remedied in a later patch.
