drm/doc: Document kapi doc expectations

Browse Source 
We've had this already for anything new. With my drm_prime.c cleanup I
also think documentation for everything already existing is complete,
and we can bake this in as a requirements subsystem wide.

v2: Improve wording a bit (Laurent), fix typo in commit message (Sam).

Documentation Requirements for kAPI
-----------------------------------
All kernel APIs exported to other modules must be documented, including their
datastructures and at least a short introductory section explaining the overall
concepts. Documentation should be put into the code itself as kerneldoc comments
as much as reasonable.
Do not blindly document everything, but document only what's relevant for driver
authors: Internal functions of drm.ko and definitely static functions should not
have formal kerneldoc comments. Use normal C comments if you feel like a comment
is warranted. You may use kerneldoc syntax in the comment, but it shall not
start with a /** kerneldoc marker. Similar for data structures, annotate
anything entirely private with ``/* private: */`` comments as per the
documentation guide.

Add missing kerneldoc for exported functions
--------------------------------------------
The DRM reference documentation is still lacking kerneldoc in a few areas. The
task would be to clean up interfaces like moving functions around between
files to better group them and improving the interfaces like dropping return
values for functions that never fail. Then write kerneldoc for all exported
functions and an overview section and integrate it all into the drm book.
See https://dri.freedesktop.org/docs/drm/ for what's there already.
