Future non-MTL platforms may re-use this IP and will need to follow the exact same logic and apply the same workarounds. IS_MTL_DISPLAY_STEP() is dropped in favor of a new macro IS_DISPLAY_IP_STEP() that only checks the display IP version. v2: - Rename macro to IS_DISPLAY_IP_STEP for consistency with the corresponding GT macro and handle steppings the same way. v3: - Drop the automatic "STEP_" pasting.
