Add the YAML arch to the linux-nvgpu repo so that the arch and source
code can be kept entirely in sync.
When the YAML was in a separate repo it was too difficult to keep things
in sync. Based on this work the next steps are:
1. Gate compilation on no sources issues (missing or orphan source
files.
2. Perhaps use the arch to generate the Makefile.sources files.
