The fence is only tracking if the HuC load is in progress or not and
doesn't distinguish between already loaded, not supported or disabled,
so we can always initialize it to completed, no matter the actual
support. We already do that for most platforms, but we skip it on
GTs that lack VCS engines (e.g. MTL root GT), so fix that. Note that the
cleanup is already unconditional.
While at it, move the init/fini to helper functions.

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.
