[Why] Pitch, DCC, rotation and mirroring can result in updates that are not UPDATE_TYPE_FAST but UPDATE_TYPE_MED instead. DC needs dc_plane_info and dc_plane_size to make this determination and we aren't currently passing this into DC during atomic check. Underflow (visible or non-visible) can occur if we don't validate this correctly. This also will generally trigger p-state warnings, typically via the cursor handler when locking. [How] Get the framebuffer tiling flags and generate the required structures for DC in dm_determine_update_type_for_commit.
