i2c: add i2c driver for stm32
Add i2c driver which can be used on both STM32F7 and STM32H7.
This I2C block supports the following features:
_ Slave and master modes
_ Multimaster capability
_ Standard-mode (up to 100 kHz)
_ Fast-mode (up to 400 kHz)
_ Fast-mode Plus (up to 1 MHz)
_ 7-bit and 10-bit addressing mode
_ Multiple 7-bit slave addresses (2 addresses, 1 with configurable mask)
_ All 7-bit addresses acknowledge mode
_ General call
_ Programmable setup and hold times
_ Easy to use event management
_ Optional clock stretching
_ Software reset
