[PATCH 0/3] gpu: nova-core: unload extras for Hopper/Blackwell

[Eliot Courtney]

This has a few patches for what I had to do to get driver unload/reload
working for Hopper/Blackwell. This depends on John's Blackwell series
and Alex's unload series, although neither apply cleanly on latest
drm-rust-next for me so this might not apply as is, but hopefully can be
integrated into the other series or something as needed.

It's just two steps:
1. Make sure FSP didn't have any old message lying around that it hadn't
   consumed, which I observed sometimes happened to me on unload/reload.
2. Wait for GSP falcon to halt.
