drm/nouveau/gr/gf100-: virtualise alpha_beta_tables + improve algorithms
I haven't yet been able to find a fully programatic way of calculating the
same mapping as NVIDIA for GF100-GF119, so the algorithm partially depends
on data tables for specific configurations.
I couldn't find traces for every possibility, so the algorithm will switch
to a mapping similar to what GK104-GM10x use if it encounters one. We did
the wrong thing before anyway, so shouldn't matter too much.
The algorithm used in the GK104 implementation was ported from NVGPU.
