205e18c135 nouveau/gsp: handle engines in runl without nonstall interrupts.
It appears on TU106 GPUs (2070), that some of the nvdec engines
are in the runlist but have no valid nonstall interrupt, nouveau
didn't handle that too well.

This should let nouveau/gsp work on those.

Fetches the interrupt table from RM, and hooks up the GSP interrupt
handler to message queue processing to catch async messages.

176fdcbddf drm/nouveau/gsp/r535: add support for booting GSP-RM
This commit adds the initial code needed to boot the GSP-RM firmware
provided by NVIDIA, bringing with it the beginnings of Ada support.

Until it's had more testing and time to bake, support is disabled by
default (except on Ada).  GSP-RM usage can be enabled by passing the
"config=NvGspRm=1" module option.

015ef6187f drm/nouveau/gsp: prepare for GSP-RM
- move TOP after GSP, so we can disable TOP if GSP is in use
- provide plumbing to support falcon-only and GSP-RM paths
- provide a method for subdevs to detect GSP-RM paths
- split tu102/tu116/ga100 paths from gv100, which can't support GSP-RM

9c28abb7db drm/nouveau/subdev: store full subdev name in struct
Much easier to store this to avoid having to reconstruct a string for a
specific subdev, taking into account whether it's instanced or not.

334815ef31 drm/nouveau/gsp: initialise SW state for falcon from constructor
This will allow us to register the falcon with ACR, and further customise
its behaviour by providing the nvkm_falcon_func structure directly.
