gpu: nvgpu: add nvgpu-next infrastructure

Browse Source 
* As of now, working on multiple chip bringup in nvgpu-next repo has
   an issue because we end with losing control on source code (hard to
   find which part of the code belongs to which chip) and it's valuable
   history this affects chip migration on release.

 * To support multiple chip bringup simultaneously, we need new
   guidelines to avoid losing control on source code and make migration
   easier. This change adds links to nvgpu-next repo.

 * Updated return code to ENODEV for consistency
 * Updated ACR unittest to work with ENODEV return code

NOTE:
     These are the initial set of infrastructure changes, guidelines
     will evolve, and source code will get updated accordingly.

     Based on future chip features, Which part of the source code falls
     under nvgpu-next repo is decided.
