These two functions are unused in some configurations, and using __maybe_unused
is the easiest way to shut up the harmless warnings:

drivers/gpu/drm/bridge/cdns-dsi.c:1353:12: error: 'cdns_dsi_suspend' defined but not used [-Werror=unused-function]
 static int cdns_dsi_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~
drivers/gpu/drm/bridge/cdns-dsi.c:1340:12: error: 'cdns_dsi_resume' defined but not used [-Werror=unused-function]
 static int cdns_dsi_resume(struct device *dev)

Fixes: e19233955d9e ("drm/bridge: Add Cadence DSI driver")

Hm, I thought such a patch had already been applied by Thierry [1].

Yeah, that's in drm-misc-next, but didn't seem to have made it into
linux-next until today.
