There is a well-agreed-apon legal format for copyright lines already,
and those lines should be fine in the comment text at the top of the
file.  No need to mess with SPDX-FileWhateverTagWeWant type of stuff
here at all as all of our tools can easily find those lines if they
really want to extract the copyright information.

SPDX is great for license declarations, let's stick with only using that
for now until we finish the whole kernel and then maybe we can worry
about adding additional meta information if it's really decided it can
benifit anyone.

For now, copyright lines don't seem worth it to me, just leave them in a
comment block please.
