PSR2 apparently requires some planes to be enabled for some silly reason, and so we are now trying to turn PSR off before planes go off. Except during a full modeset that is handled less clearly through reorganization of the modeset sequence. That is not great as it makes the code mode complex, and prevents us from doing nice things such as just turning off all the planes at the very start of the modeset. So let's move the PSR pre_plane_update() thing to a spot where it will handle both full modesets and everything else.

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.
