Add driver for the Intersil ISL7998x Analog to MIPI CSI-2/BT656 decoder. This chip supports 1/2/4 analog video inputs and converts them into 1/2/4 VCs in MIPI CSI2 stream. This driver currently supports ISL79987 and both 720x480 and 720x576 resolutions, however as per specification, all inputs must use the same resolution and standard. The only supported pixel format is now YUYV/YUV422. The chip should support RGB565 on the CSI2 as well, but this is currently unsupported.

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.
