[PATCH] nvidia: add acr/bl symlink for booting GSP-RM on GA100

[Timur Tabi]

The Nvidia GA100 is a compute-only (no display hardware) Ampere GPU that
boots like a Turing (TU10x) GPU.  Consequently, it needs the same kind of
firmware images that Turing does.  Since Nouveau looks for all images
in GPU-specific directories, all of the firmware files that GA100 needs
must be reachable in the nvidia/ga100/ directory.

The ACR bootloader (acr/bl.bin, aka Generic Bootloader), is used normally
by Nouveau to support Turing and Ampere GPUs, both with and without
GSP-RM.  However, there is still significant code missing in Nouveau to
support non-GSP GA100.  Consequently, the firmware files that would
be used by Nouveau to support non-GSP GA100 are not included.

Since GA100 uses the same ACR bootloader as TU102, all that is needed is
a symlink.
