drm/amdgpu: Create version number for coredumps 



Even if there's nothing currently parsing amdgpu's coredump files, if
we eventually have such tools they will be glad to find a version field
to properly read the file.

Create a version number to be displayed on top of coredump file, to be
incremented when the file format or content get changed.
