Move more display specific parts of GPU error logging behind the display snapshot interface. With the display register capture reduced to just one register, DERRMR, there's quite a bit of boilerplate here. However, it's still a nice abstraction and removes a DISPLAY_VER() usage from core i915. With this approach, it's also easy to add to xe as needed. v2: Remove stale comment Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://lore.kernel.org/r/13206969df04426d290d2863dc574e22ca45193a.1744630147.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>
