Putting the panel under the bridge chip (under the aux-bus node) allows the panel driver to get access to the DP AUX bus, enabling all sorts of fabulous new features. While we're at this, get rid of a level of hierarchy for the panel node. It doesn't need "ports / port" and can just have a "port" child. For Linux, this patch has a hard requirement on the patches adding DP AUX bus support to the ti-sn65dsi86 bridge chip driver. See the patch ("drm/bridge: ti-sn65dsi86: Add support for the DP AUX bus").
