Protect the suspend and resume callbacks with an #ifdef CONFIG_PM_SLEEP guard to avoid "defined but not used" warnings.

The best solution would be to merge legacy exynos_drm_(suspend|resume) PM functions with exynos_drm_sys_(suspend|resume). There is no reason to keep both. Could you do it, if not I can prepare quick patch.
