drm/amdgpu: Add trace events for pid register/deregister

Browse source

Some debugging applications need to track when a process starts
or stops using the amdgpu driver. For those processes, add ftrace
events that track when a amdgpu_vm task info is changed or destroyed.

v2: Deregister in fini, not destroy.

v3: Also report render minor and major
