Ville Syrjälä 841f262e74 drm/i915: Fix up skl_program_plane() pxp stuff
There's lots of expensive stuff inserted between the PLANE_CTL
and  PLANE_SURF writes even though the comment before the PLANE_CTL
write says not to put stuff there. Move it all to a more apporiate
place.

There's also a weird PLANE_COLOR_CTL RMW in there. I guess because
force_black was computed way too late originally, but that is now
sorted.

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.
