Just like we did for pipe gamma, let's also track the pipe csc
state. The hardware only exists on ILK+, and currently we always
enable it on hsw+ and never on any other platforms. Just like
with pipe gamma, the primary plane control register is used
for the readout on pre-SKL, and the pipe bottom color register
on SKL+.
v2: Rebase
v3: Allow fastboot with csc_enable changes (Maarten)
Deal with HAS_GMCH

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.
