This patch adds the support of I2C_SMBUS_I2C_BLOCK_DATA transaction type for the stm32f7 SMBUS Controller. Use emulated I2C_SMBUS_I2C_BLOCK_DATA transactions as there is no specific hardware in STM32 I2C to manage this (e.g. like no need for PEC here). Emulated transfer will fall back calling i2c transfer method where there's already support for DMAs for example. So, use the I2C_FUNC_SMBUS_I2C_BLOCK in stm32f7_i2c_func(), and rely on emulated transfer by returning -EOPNOTSUPP in the smbus_xfer() routine for such a case.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
