usb: musb: blackfin: fix unused warnings on suspend/resume
When CONFIG_PM_SLEEP is disabled, SIMPLE_DEV_PM_OPS does not use bfin_resume and bfin_suspend even if CONFIG_PM is enabled: drivers/usb/musb/blackfin.c:602:12: warning: ‘bfin_resume’ defined but not used [-Wunused-function] static int bfin_resume(struct device *dev) ^~~~~~~~~~~ drivers/usb/musb/blackfin.c:585:12: warning: ‘bfin_suspend’ defined but not used [-Wunused-function] static int bfin_suspend(struct device *dev) ^~~~~~~~~~~~ The preprocessor condition should be on CONFIG_PM_SLEEP, not on CONFIG_PM. However it is better to mark these functions as __maybe_unused.
