Add skl_wm_plane_disable_noatomic() which will clear out all the ddb and wm state for the plane. And let's do this _before_ we call plane->disable_arm() so that it'll actually clear out the state in the hardware as well. Currently this won't do anything new for most of the intel_plane_disable_noatomic() calls since those are done before wm readout, and thus everything wm/ddb related in the state will still be zeroed anyway. The only difference will be for skl_dbuf_sanitize() is happens after wm readout. But I'll be reordering thigns so that wm readout happens earlier and at that point this will guarantee that we still clear out the old wm/ddb junk from the state.

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.
