Some SoC without MMU have display driver where a drm/kms driver
could be implemented.
Before doing such kind of thing drm/kms must allow to use mmuless devices.
This patch propose to remove MMU configuration flag and add a cma helper
function to help implementing mmuless display driver
version 4:
- add documentation about drm_gem_cma_get_unmapped_area()
- stub it MMU case

Added some boilerplate for the structs, documented members where they
are relevant and plenty of markup for hyperlinks all over. And a few
small wording polish.
Note that the intro needs some more love after the DRM_MM_INSERT_*
patch from Chris has landed.
v2: Spelling fixes (Chris).
v3: Use &struct foo instead of &foo structure (Chris).

ttm_global_reference was renamed to drm_global_reference. This updates
the documentation to reflect that. While we are there, document the
drm_global_reference API and update the initialization interface
documentation.

Now that we don't have automatic syntax highlighting, use the code-block
directive with the explicitly selected language, where appropriate.

- Readjust headings - we lost one level through the extraction into a
separate .rst file.
- Merge helper reference sections with the helper documentation - that
split was just an artifact of the docbook toolchain sucking at too
deep nesting levels. No such problems with sphinx.
- Move the cma helpers in with the gem documentation, since they're
helpers to implement gem using CMA/dma memory as a backend.
