We shouldn't really be keeping track of how many SFC_DONE registers our platforms can have, but rather how many SFC hardware units there can be (each SFC unit will have one corresponding SFC_DONE register). So drop the stray GEN12_SFC_DONE_MAX definition we had in the register definition file and replace it with an I915_MAX_SFC that follows the pattern we use for other hardware units. Note that our hardware has a 2:1:1 ratio of VD:VE:SFC, and as far as we know that pattern should carry forward to future platforms, so we'll define it as #VCS/2.

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.
