Eliminate the PIPECONF RMWs from .comit_commit() so that we can finally declare the whole vblank evade part (and the noarm() part) of the pipe commit free of register reads. Or at least I hope that's the last read... Only the i9xx/ilk codepaths need this for now, but let's add the same thing for hsw+ just in case we want to start calling that during fastsets at some point (eg. to change dithering settings/etc.). Should open up the way to start experimenting with different DSB usage approaches for pipe commits.

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.
