    drm/nouveau/gr: use NVIDIA-provided external firmwares

    NVIDIA will officially start providing GR firmwares through
    linux-firmware for GPUs that require it. Change the GR firmware lookup
    function to use these files.

fuc409c -> fecs_inst
fuc409d -> fecs_data
fuc41ac -> gpccs_inst
fuc41ad -> gpccs_data

And it wants the files to live in nvidia/gk106/ (or whatever the relevant chip
name).

Ben's belief is that everyone should be fine with nouveau firmware, and the
fact that the nvidia firmware works at all with nouveau is a fluke.
