We have two identical copies of the snb+ system agent CPU fence programming code. Extract into a helper. Also there's no real point in insisting that we program 0 into DPFC_CPU_FENCE_OFFSET when the fence is disabled. So just always stick the computed Y offset there whether or not the fence is actually used or not.

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.
