Greg Kroah-Hartman 98a95b9cc9 staging: octeon: remove redundant license text
Now that the SPDX tag is in all drivers/staging/octeon/ files, that
identifies the license in a specific and legally-defined manner.  So the
extra GPL text wording can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.
