drm/i915: Replace several IS_METEORLAKE with proper IP version checks
[ Upstream commit 14128d64090fa88445376cb8ccf91c50c08bd410 ]
Many of the IS_METEORLAKE conditions throughout the driver are supposed
to be checks for Xe_LPG and/or Xe_LPM+ IP, not for the MTL platform
specifically. Update those checks to ensure that the code will still
operate properly if/when these IP versions show up on future platforms.
v2:
- Update two more conditions (one for pg_enable, one for MTL HuC
compatibility).
v3:
- Don't change GuC/HuC compatibility check, which sounds like it truly
is specific to the MTL platform. (Gustavo)
- Drop a non-lineage workaround number for the OA timestamp frequency
workaround. (Gustavo)
