[PATCH 2/3] Documentation/gpu: Limit index to maxdepth=2

[Lucas De Marchi <lucas.demarchi@intel.com>]

With a lot of sub-section it's a little bit hard to find the information
needed in the main GPU index. Limit the maxdepth to 2 so it doesn't get
poluted with noise from each driver and from other sections.
