This patch re-introduces support for GuC v69 in parallel to v70. As this is a quick fix, v69 has been re-introduced as the single "fallback" guc version in case v70 is not available on disk and only for platforms that are out of force_probe and require the GuC by default. All v69 specific code has been labeled as such for easy identification, and the same was done for all v70 functions for which there is a separate v69 version, to avoid accidentally calling the wrong version via the unlabeled name. When the fallback mode kicks in, a drm_notice message is printed in dmesg to inform the user of the required update. The existing logging of the fetch function has also been updated so that we no longer complain immediately if we can't find a fw and we only throw an error if the fetch of both the base and fallback blobs fails. The plan is to follow this up with a more complex rework to allow for multiple different GuC versions to be supported at the same time. v2: reduce the fallback to platform that require it, switch to firmware_request_nowarn(), improve logs.

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.
