Convert everything except uncore access to struct intel_display. Converting the graphics version checks to display version checks needs a tweak for display version 13, which have graphics version 12. While at it, convert logging to drm_dbg_kms(). v2: Handle display version 13 Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patch.msgid.link/20251120161846.3128999-1-jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>
