gpu: nvgpu: Add YAML arch to linux-nvgpu

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.
