9bdb8f1a10 gpu: nvgpu: Correct LS ucode data alignment. 
Currently LS UCODE data is aligned to PAGE_SIZE
which is dependent on kernel config.

This causes "data_size" variable to change due to
padding difference which causes LS sig authentication
to fail.

This patch corrects alignment and align it to
LSF_UCODE_DATA_ddALIGNMENT instead of PAGE_SIZE.

dd9b4364aa gpu: nvgpu: add nvgpu-next infrastructure 
* 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.

This change adds lsf_ucode_desc_wrapper to hold the pkc signature
header and corresponding lsf_lsb_header_v2. During blob preparation
based on the flag is_sig_pkc, the new header defines will be
packed into ls blob and passed to acr.
The flag NVGPU_PKC_LS_SIG_ENABLED is also added, which will be set
based on the acr core selection.
