[0/1] drm/amdgpu: Use device wedged event

Message

Raag Jadav is introducing a new DRM API for generating "device wedged events",
to notify userspace when the device needs userspace intervention after a GPU
reset[1]. I did a simple patch to add support for it for amdgpu for the
telemetry aspect of the event. Tested in Steam Deck. This patch requires [1] to
be applied.

Raag, if you are sending a v11 of your work you can carry this patch as well if
you think it makes sense.

great, more users

when this started the plan was to merge it through drm-xe since xe was
the only user. Now we already have 3, so I think it makes sense to go
through drm-misc... I looked at the possible conflicts in i915 and xe
and they are minimal.

thanks
