* Treat tiled monitors as one logical display, so the splash is drawn
once across a tiled panel such as the Dell UP3218K instead of once per
tile (LP: #2167376). Cherry-picked from upstream main:
- d/p/lp2167376-01-drm-guard-gamma-ramp-setup.patch: prerequisite, so
the following patches apply unmodified
- d/p/lp2167376-02-drm-Parse-tiled-display-metadata.patch
- d/p/lp2167376-03-drm-Select-modes-for-display-tiles.patch
- d/p/lp2167376-04-drm-Plan-tiled-display-geometry.patch
- d/p/lp2167376-05-drm-Store-scanout-state-per-controller.patch
- d/p/lp2167376-06-drm-Read-connector-tile-properties.patch
- d/p/lp2167376-07-drm-Combine-tiled-outputs-into-logical-heads.patch
