[PATCH v12 5/5] drm/amdgpu: Use device wedged event

[Raag Jadav]

From: André Almeida <andrealmeid at igalia.com>

Use DRM's device wedged event to notify userspace that a reset had
happened. For now, only use `none` method meant for telemetry
capture.

In the future we might want to report a recovery method if the reset didn't
succeed.
