[Keyboard] Added support for ErgoDox with STM32 Microcontroller (#5398)

Browse source 
* Began Work On STM32 Ergodox
 Changes to be committed:
	new file:   keyboards/ergodox_stm32/config.h
	new file:   keyboards/ergodox_stm32/rules.mk

* test

* Now it compile. Not linking thou

* Screw this Linker. It links now!

* Blinkly Keyboard

* bootloader test code

* Working on matrix / i2c stuff

* Progress (LED Blink)

* Progress on MCP_23017 Status Flag

* [WIP]

* update

* Works! Remeber to change back the bootloader address when the new bootloadrer is ready.

* Time to go debug the i2c

* Finally, it now works with PCB Rev 1.0.2

* updated for rev.2 pcb

* minor compilation fix

* Why when debugger is enabled then everything works.

* Remeber to call init functions.

* Update arm i2c driver to support STM32F103 series device.

* fix include once header. Replaced with #pragma once.

* complication test
