Venkata Sandeep Dhanalakota 442e049aed drm/i915/gen12: Use fuse info to enable SFC
In Gen12 there are various fuse combinations and in each configuration
vdbox engine may be connected to SFC depending on which engines are
available, so we need to set the SFC capability based on fuse value from
the hardware. Even numbered physical instance always have SFC, odd
numbered physical instances have SFC only if previous even instance is
fused off.

v2:
 - Minor style & typo fixes (Tvrtko)
 - Drop an unwanted 'inline' (Tvrtko)

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.
