Documentation/gpu: add new gpu.rst converted from DocBook gpu.tmpl
This is the first step towards converting the DocBook gpu.tmpl to Sphinx and reStructuredText, the new kernel documentation tool and markup. Use Jon's "cheesy conversion script" in Documentation/sphinx/tmplcvt to do the rough conversion. Do the manual edits in follow-up patches. Add a new Documentation/gpu directories for the graphics related documentation. (Hooray, now we can have directories based on topics rather than tools under Documentation.) We also won't remove the DocBook gpu.tmpl yet so it's easier to build both and compare the results for parity.
