We don't have proper watermark NV12 support on ICL due to differences in how it should be implemented. In commit234059da0f("drm/i915/icl: NV12 y-plane ddb is not in same plane") we avoided writing the non-existent PLANE_NV12_BUF_CFG registers but we forgot to also avoid them on the hardware state readout. While the code is still not correct, at least now we can avoid unclaimed register error messages when dealing with RGB formats, which makes CI happier. Also add some FIXME comments in order to make it even more clear that there's still work to do.

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.
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.
