Subject: [PATCH] drm/amdgpu: finish GPU recovery callbacks before restarting
 schedulers

Run GPU post-reset callbacks, including KFD and display-audio resume,
before restarting DRM scheduler workqueues. IP hardware initialization
already happens inside ASIC recovery; this change orders the remaining
callbacks before new scheduler submissions. Preserve the emergency-stop
and guity job completition path's callbacks without starting schedulers,
