Thanks a lot for this, I am hitting the FLR reset bug and this has made
testing the Blackwell series so much easier! :)

I think we should take this into John's series after rebasing it on my
unload code, as without it running Blackwell through VFIO is
impractical.

I think patches 2 and 3 can be picked up as-is. For patch 1, I want to
give feedback to make the FSP command queue sounder from the get-go, so
I'm not sure whether it will still apply after that, but let me come
back to it a bit later.
