Commit 7c49abb4c2f8 ("drm/rockchip: cdn-dp-core: Make cdn_dp_core_suspend/resume static")
introduced the following warning in some builds:

cdn-dp-core.c:1124:12: warning: ‘cdn_dp_resume’ defined but not used
 1124 | static int cdn_dp_resume(struct device *dev)
      |            ^~~~~~~~~~~~~

Fix this by defining cdn_dp_resume __maybe_unused
