The GSC CS is only used for communicating with the GSC FW, so no need to initialize it if we're not going to use the FW. If we're not using neither the engine nor the microcontoller, then we can also disable the power well. IMPORTANT: lack of GSC FW breaks media C6 due to opposing requirements between CS setup and forcewake idleness. See in-code comment for detail.

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.
