Subject: drm/amd/display: Call update_stream_signal directly from amdgpu_dm
Git-commit: 9182b4cb445dc31bd46d2cc1e9e7e38771fdbae4
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
No-fix: 3549130ef7f6ec732a7770ea0ac36231be85a089

There's no good place in DC to cover all place where stream signal should
be updated. update_stream_signal depends on timing which comes from DM.
