 * Name: stm32_usbsuspend
 *
 * Description:
 *   Board logic must provide the stm32_usbsuspend logic if the USBDEV driver
 *   is used. This function is called whenever the USB enters or leaves
 *   suspend mode. This is an opportunity for the board logic to shutdown
 *   clocks, power, etc. while the USB is suspended.
 *
 * TODO:
 *   - Well... implement those features like clock shutdown.
