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.

Marek, Pierre-Eric, Bas, Sam etc.. any comments on this?

 From the kernel side the functionality is trivial, question is do you 
guys need that? If yes an ack would be nice to have.

Thanks,
Christian.
