Subject: drm: rcar-du: Remove unused CRTC suspend/resume functions
Git-commit: cf05f74ef40ed608e554f635799e831995213215
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

An early implementation of suspend-resume helpers are available in the
CRTC module, however they are unused and no longer needed.

With suspend and resume handled by the core DRM atomic helpers, we can
remove the unused functions.
