Expand and improve AMDGPU documentation

This patchset improves how the AMDGPU display documentation is
organized, expands the kerne-doc to extract information from the source,
and adds more context about DC workflow. Finally, at the end of this
series, we also introduce a contribution session for those interested in
contributing with the display code.

Thanks
Siqueira
