tipc: Add SPDX id lines to source files

[PATCH] tipc: Add SPDX id lines to source files
Posted by Tim Bird 3 days, 11 hours ago
Most of the tipc source files are missing SPDX-License-Identifier
lines.  Add appropriate IDs to these files, and remove the
previous license lines from the headers.  In this case,
every file received the 'GPL-2.0 OR BSD-3-Clause' ID expression.
