Subject: drm/amd/display: Remove dangling planes on dc commit state
Git-commit: 4faf6eddfbebba1cdc4653484b7a8c8f28bd3bff
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

When disabling pipe splitting, we need to make sure we disable both
planes used.

This should be done for Linux as well.
