 * Name:  stm32l4_usbsuspend

 * Description:
 *   Board logic must provide the stm32l4_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.
