Subject: drm/bridge: cdns: Mark runtime PM operations as maybe unused
Git-commit: eea740a98df9ff914001bd066389b6e8f1024991
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Building the driver in a configuration with !PM currently causes a
warning about these operations being unused. Mark them as such to shut
up the compiler.
