This patch adds support for the STMicroelectronics STM32F4x family in the
STM32 MCU line. Configuration is included for the STM32F401RE MCU.
Acknowledgements to Pawel Wodnicki's earlier submission from February that
was used as a starting point for this port. In the end, we rewrote all of it.

Since dd5e90ec the device_get_binding call returns NULL unless the
driver_api is set by the driver. Since the exti driver only uses an
internal struct to store the callbacks, remove the need for the device
binding call from other drivers (e.g. gpio).
