Add a test for sending messages from every GuC to every other GuC to test G2G communications. Note that, being a debug only feature, the test interface only exists in pre-production builds of the GuC firmware. v2: Fix 'default' case to actually use the driver's registration code as well as allocation. Add comments explaining the different test types. Fix (C) date and an assert. Review feedback from Daniele.

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 reStructuredText 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.
