The suspend/resume callbacks are now optional, leading to a warning when
they are unused:

drivers/gpu/drm/bridge/cdns-dsi.c:1353:12: warning: ‘cdns_dsi_suspend’
   defined but not used [-Wunused-function]
 static int cdns_dsi_suspend(struct device *dev)
drivers/gpu/drm/bridge/cdns-dsi.c:1340:12: warning: ‘cdns_dsi_resume’
   defined but not used [-Wunused-function]
 static int cdns_dsi_resume(struct device *dev)

This marks the functions as __maybe_unused to avoid the warning.
