drivers/usb/dwc3/dwc3-of-simple.c:223:12: warning: ‘dwc3_of_simple_resume’ defined but not used [-Wunused-function]

drivers/usb/dwc3/dwc3-of-simple.c:213:12: warning: ‘dwc3_of_simple_suspend’ defined but not used [-Wunused-function]
static int dwc3_of_simple_suspend(struct device *dev)
^~~~~~~~~~~~~~~~~~~~~~
This marks them as __maybe_unused to let the compiler drop the function
without complaining.
