Use intel_wm_plane_visible() to determine cursor visibility for SKL+
also. Previously SKL+ would check the actual visibility which now
conflicts with the assumptions in intel_legacy_cursor_update().
We also change SKL+ to compute the cursor watermarks based on the
unclipped cursor size, just as we do on all the other platforms.
Using the clipped size could now result in garbage results.
Testcase: igt/kms_chv_cursor_fail

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
