    nvidia: add GA102/GA103/GA104/GA106/GA107 signed firmware

    These NVIDIA-signed firmwares are required to enable the graphics engine
    on Ampere GA10{2/3/4/6/7} Gpus.

Note that our drm2 driver won't use the GA10{2/3/4/6/7} firmware yet.
The updated Tu10x and Tu11x signed firmware are needed for at last the
nvidia T400 graphic card.
