Subject: drm/amd/display: Fix FBC disable for stereo
Git-commit: 57d972d4927581d027007c92b57b843c186128d4
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Removed FBC disable from dc_enable_stereo().
It should be implemented in stereo_setup callback, which is not
implemented yet. Otherwise it always disable FBC regardless
if stereo supported or not.
