drm/nouveau/gsp: require GSP-RM for GA100 support

Browse source

Nouveau supports Turing and Ampere GPUs with or without GSP-RM.
Support without GSP-RM is mostly academic, since GSP-RM is
needed to run the GPU at full clocks.  It is also the default
mode for these GPUs.

GA100 is a special case, however.  The current code has some support
for running GA100 without GSP-RM, but several features are missing.
More importantly, some required firmware images like ucode_ahesasc.bin
are not available and would need to be provided by Nvidia.

To prevent Nouveau from even trying to boot on GA100 without GSP-RM,
remove the non-GSP fallback option in the ga100_gsps[] array.
