Subject: drm/amd/display: remove surface validation against stream rect
Git-commit: 934d292316b5d3933d7fe6811c5d7a696c33910c
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Surface information is by default copied from old context in dc_commit_stream.
Thus unchange streams will not be affected. For new streams, we shouldn't
validate the new mode against the surface configuration of old_context.
