Get rid of intel_frontbuffer_flip_{prepare,complete}() from
the overlay code and just use intel_frontbuffer_flip() instead.
The only difference between these are the light interactions
with the ORIGIN_CS busyness tracking, but since the only user
of this is the overlay/xf86-video-intel/Xv the buffer will
always be filled by the CPU and thus we'll never see any
ORIGIN_CS frontbuffer activity there anyway. Also I don't
think we actually have anything covered by the frontbuffer
tracking that affects the overlay (FBC is on the primary
plane, DRRS isn't currently enabled on the platforms with
overlay, and PSR doesn't exist in the hardware).

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 reStructuredText 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.
