4ae3a20102 nouveau/gsp: don't free ctrl messages on errors 
It looks like for some messages the upper layers need to get access to the
results of the message so we can interpret it.

Rework the ctrl push interface to not free things and cleanup properly
whereever it errors out.

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
