yiancar 621ce29a53 STM32 EEPROM Emulation (#3741)
* STM32 EEPROM Emulation

- Added EEPROM emulation libaries from libmaple and Arduino_STM32. https://github.com/rogerclarkmelbourne/Arduino_STM32 and https://github.com/leaflabs/libmaple.
- Renamed teensy EEPROM library and added conditional selection of library.
- Remapped EEPROM memory map for 16 byte blocks (as is with STM32f3xx MCUs).
- Added EEPROM initialization in main.c of Chibios.
- Added EEPROM format to clear the emulated pages when EEPROM is marked as invalid.

* Fixed ifdef
