[PATCH kernel] powerpc/powernv/npu: Export symbols as GPL

[Alexey Kardashevskiy]

The out-of-tree NVIDIA driver has been re-licensed recently to MIT/GPL
so we can do the right thing and restrict the exported symbols to GPL
only.

Which still does not matter until it actually is in mainline.  We don't
keep kernel infrastructure for purely out of tree drivers around.
