Merge #2223

2223: Stack size update for STM32F4 boards r=hudson-ayers a=alexandruradovici ### Pull Request Overview This pull request fixes the stack size requirement for STM32F4 boards. Due to the new board instantiation #2188, the required stack size has to be doubled as @hudson-ayers suggested in #2188 (comment). ### Testing Strategy This pull request was tested using an STM32f412GDiscovery board. ### TODO or Help Wanted @krady21, @cosmindanielradu19, @teonaseverin please test using the ~STM32F3Discovery and~ Nucleo. Running the blink app is just enough. ### Documentation Updated - [x] Updated the relevant files in `/docs`, or no updates are required. ### Formatting - [x] Ran `make prepush`.
