arm: st_stm32: Add support for STM32F4x SoC family
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.
