Documentation: gpu: add acceleration node section

Hi everyone,

There is a missing section of GPU documentation on Acceleration Nodes. This patch adds a stubbed section to be filled in. I was able to render the new section as a PDF.

make SPHINXDIRS="gpu/" pdfdocs

Changes since v1:
- Comments from Bagas. Change from note admonition to generic admonition
