Asmaa Mnebhi 86067ccfa1 i2c: mlxbf: support lock mechanism
Linux is not the only entity using the BlueField I2C busses so
support a lock mechanism provided by hardware to avoid issues
when multiple entities are trying to access the same bus.

The lock is acquired whenever written explicitely or the lock
register is read. So make sure it is always released at the end
of a successful or failed transaction.

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.
