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 v2:
- Group I2C pins definitions in the device tree (Maxime)
- Suffix I2C phandle with part number (Maxime)
- Remov busy variable as not used (Rajeev)
- Rename STM32F4_I2C_TRISE_TRISE macro (Rajeev)
- Remove magic number during rise time computation (Rajeev)
- Simplify speed mode function computation
