[PATCH v6 0/5] Add support for the STM32F4 I2C

[M'boumba Cedric Madianga]

This patchset adds support for the I2C controller embedded in STM32F4xx SoC.
It enables I2C transfer in interrupt mode with Standard-mode and Fast-mode bus
speed.

Changes since v5:
- Change commit header from "ARM: dts:" to "ARM: dts: stm32:" (Alex)
- Change commit header from "ARM: configs:" to "ARM: configs: stm32:" (Alex)
- Fix warnings due to variable set but unused (Wolfram)
- Remove double space in Kconfig (Wolfram)
- Fix warning due to bad type parameter when using clamp() function
  (build-bot)
