This is just refactoring to allow the lower layers to distinguish
between suspend and runtime suspend.

GSP 570 needs to set a flag with the GPU is going into GCOFF,
this flag taken from the opengpu driver is set whenever runtime
suspend is enterning GCOFF but not for normal suspend paths.

This just refactors the code, a subsequent patch use the information.

This commit adds support for the GB20x GPUs found on GeForce RTX 50xx
series boards.

Beyond a few miscellaneous register moves and HW class ID plumbing,
this reuses most of the code added to support GH100/GB10x.

With minimal to no direct HW programming required, most nvkm_engine
implementations are nearly identical when running on top of GSP-RM.

Add a common implementation of the boilerplate, and use nvkm_rm_gpu to
expose the correct class IDs.

As they're now handled by common code, and there's no support for them
prior to GSP-RM support - this deletes the GA100 NVDEC/NVJPG/OFA HALs,
the GA102 NVENC/OFA HALs, and the AD102 GR/NVDEC/NVENC/NVJPG/OFA HALs.

Move all the remaining GSP-RM code together underneath a versioned path,
to make the code easier to work with when adding support for a newer RM
version.

Aside from adjusting include paths, no code change is intended.

This moves the initial effort to the latest 535 firmware.

The gsp msg structs have changed, and the message passing also.
The wpr also seems to have some struct changes.

This version of the firmware will be what we are stuck on for a while,
until we can refactor the driver and work out a better path forward.

GSP-RM will enforce this, so implement on HW too so we can share code.
