Without CONFIG_PM, we get a harmless build warning:

drivers/media/i2c/ov2685.c:516:12: error: 'ov2685_runtime_suspend' defined but not used [-Werror=unused-function]
 static int ov2685_runtime_suspend(struct device *dev)
            ^~~~~~~~~~~~~~~~~~~~~~
drivers/media/i2c/ov2685.c:507:12: error: 'ov2685_runtime_resume' defined but not used [-Werror=unused-function]
 static int ov2685_runtime_resume(struct device *dev)

This marks the affected functions as __maybe_unused.

Fixes: e3861d9118c8 ("media: ov2685: add support for OV2685 sensor")
