* Description:
* If USB is supported and the board supports a pullup via GPIO (for USB software
* connect and disconnect), then the board software must provide stm32_pullup.
* See include/nuttx/usb/usbdev.h for additional description of this method.

* 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.
