This commit enables basic support for Hopper GPUs, and is intended
primarily as a base supporting Blackwell GPUs, which reuse most of
the code added here.
Advanced features such as Confidential Compute are not supported.
Beyond a few miscellaneous register moves and HW class ID plumbing,
the bulk of the changes implemented here are to support the GSP-RM
boot sequence used on Hopper/Blackwell GPUs, as well as a new page
table layout.
There should be no changes here that impact prior GPUs.

Add r570-specific HAL routines, and support loading of GSP-RM version
570.144 if firmware is available.
There should be no impact on r535, or non-GSP paths.

545.23.06 increases the libos3 heap size requirements, and GH100/GBxxx
will need their own implementation entirely.

With GSP-RM handling the majority of the HW programming, NVKM's usual
HALs are more elaborate than necessary, resulting in a fair amount of
duplicated boilerplate.
Adds 'nvkm_rm_gpu' which serves to provide GPU-specific constants and
functions in a more streamlined manner.
This is initially used in subsequent commits to store engine class IDs,
and replace the per-engine/engobj boilerplate with common code for all
GSP-RM supported engines - and is further extended when adding GH100,
GB10x and GB20x support.

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.

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.

- 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

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.

This will allow us to register the falcon with ACR, and further customise
its behaviour by providing the nvkm_falcon_func structure directly.
