[PATCH v2 00/39] drm/i915: fix kernel-doc issues

[Mauro Carvalho Chehab <mchehab@kernel.org>]

There are several kernel-doc markups along the i915 driver that aren't part
of the i915.rst file, nor are included on any other file under Documentation.
Maybe due to that, there are several kernel-doc markups that report problems
when checked with scripts/kernel-doc. More than that, some of them also
have problems when actually integrated at the building system, as reported
by Sphinx.

Along the issues we have:

- renamed symbols where the prototype doesn't match the kernel-doc name;
- some markups doesn't have the symbol name on it;
- typos when defining parameter;
- some parameters are missing;
- some ascii artwork aren't properly displayed after parsed by Sphinx;
- some other tags produce bad results and warnings after parsed by html build;
- some "/**" patterns exist on places that aren't kernel-doc markups.

This series, against drm-tip, fix all the above issues and all all such files to
i915.rst. This way, it will be easier to avoid other problems to be introduced.

While here, I also added SPDX on two display files. Besides being the current
way to indicate the license, it also makes easier to find all files with kernel-doc
markups, as all it is needed is to search for "/**" at i915 files to know what of
them have embedded documentation.

PS.: my end goal here is to ensure that the TLB patch series I'm about to
send will be properly documented. For that to happen, let's first fix all
warnings when building the documentation ;-)

---

v2:
- Added 3 already-existing patches form other PRs addressing some of the
  issues. The subjects were renamed, in order to describe what they're
  doing.
- Fixed checkpatch warnings;
- Added 4 additional patches at the end, documenting some structs
  at i915_gem_object_types.h and  intel_gt_pm.h, plus adding 
  intel-guc.c internal functions to the generated documentation.
