Add basic support for Maxim MAX96712 quad GMSL2 deserializers. The driver is capable of powering on the device and configuring the MIPI CSI-2 bus in a DPHY 4-lane configuration as well as operating the internal VTG (Video Timing Generator) and VPG (Video Pattern Generator). Using these features the driver is able to act as a 1080p @ 30 fps V4L2 video source. Producing either a checkerboard or gradient pattern on the CSI-2 bus, selectable thru a V4L2 control. While the driver is useful as-is and have been used to prove the correct operation of the MAX96712 itself and "downstream" devices using the MAX96712 as a video source there are a lot of features missing. Most notably the ability to operate the GMSL bus.

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.
