aa5e38dc9f drm/nouveau/gr/gf100-: virtualise r419f78 + apply fixes from traces 
Removed from GK110[B]/GK208 as RM traces show it not being touched.

60770fa28b drm/nouveau/gr/gf100-: virtualise dist_skip_table + improve algorithm 
The algorithm for GM200 and newer matches RM for all the boards I have, but
I don't have enough data to try and figure something out for earlier boards,
so these will still write zeroes to the table as we did before.

The code in NVGPU isn't helpful here, it appears to handle specific cases.

c4a2b6385d drm/nouveau/gr/gf100-gf119: modify max_ways_evict where required 
I don't think this is done after Fermi, NVGPU used to do it but removed
the code, and I've not seen RM traces touching it either.

43952c6f43 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.

4f2fc25c0f drm/nouveau/fifo/gk104-: poll for runlist update completion 
Newer HW doesn't appear to send this event, which will cause long delays
in runlist updates if they don't complete immediately.

RM doesn't use these events anywhere, and an NVGPU commit message notes
that polling is the preferred method even on HW that supports the event.

a7cf01809b drm/nouveau/fifo/gk104-: require explicit runlist selection for channel allocation 
We didn't used to be aware that runlist/engine IDs weren't the same thing,
or that there was such variability in configuration between GPUs.

By exposing this information to a client, and giving it explicit control
of which runlist it's allocating a channel on, we're able to make better
choices.

The immediate effect of this is that on GPUs where CE0 is the "GRCE", we
will now be allocating a copy engine running asynchronously to GR for BO
migrations - as intended.
