drm: update todo.rst

Just drive-by, but we have gsoc running so better to update it now.

Great news is that two entries can be removed because essentially all
done.

v2: Keep a bunch of the todos, Gabriel is working on them.

 With the recent ``drm_bus`` cleanup patches for 3.17 it is no longer required

-Better kerneldoc
-----------------

-This is pretty much done, but there's some advanced topics:
-
-Come up with a way to hyperlink to struct members. Currently you can hyperlink
-to the struct using ``#struct_name``, but not to a member within. Would need
-buy-in from kerneldoc maintainers, and the big question is how to make it work
-without totally unsightly
-``drm_foo_bar_really_long_structure->even_longer_memeber`` all over the text
-which breaks text flow.
-
-Figure out how to integrate the asciidoc support for ascii-diagrams. We have a
-few of those (e.g. to describe mode timings), and asciidoc supports converting
-some ascii-art dialect into pngs. Would be really pretty to make that work.
