drm/amd/dm: Understand why attaching path/tile properties are needed

Browse source 
[ Upstream commit 04ac4b0ed412f65230b456fcd9aa07e13befff89 ]

Path property is used for userspace to know what MST connector goes to what actual DRM DisplayPort connector, the tiling property is for tiling configurations. Not sure what else there is to figure out.
