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.
