[PATCH 0/4] gpu: nova-core: gsp: cmdq: preparatory changes for r000 support

[Alexandre Courbot]

This series contains patches 5, 6 and 8 from John's r000 series v3 [1]
that prepare the command queue so that the r000 switch applies more
cleanly. They are submitted separately to make review and merging
faster, and because they are also valuable even without the r000 switch.

Patch 1 is a drive-by fix of the `NV_PFSP` register declarations that is
included here as the `NV_PGSP` declarations mirror the `NV_PFSP` ones.

No functional change is introduced by this series.

Applies cleanly on `drm-rust-next`, and runtime-tested successfully on
Ampere.
