Subject: drm: qxl: Remove unused CRTC .dpms() helper operation
Git-commit: 4889b35d7fa1d211ff8246fae514800e07fb0099
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The CRTC .dpms() helper operation is called by the atomic helpers only
when no .prepare(), .atomic_disable() or .disable() operation is
provided. As the qxl driver provides a .disable() operation, the .dpms()
operation is unused and can be removed.
