Patrick Georgi 02363b5e46 treewide: Move "is part of the coreboot project" line in its own comment
That makes it easier to identify "license only" headers (because they
are now license only)

Script line used for that:
  perl -i -p0e 's|/\*.*\n.*This file is part of the coreboot project.*\n.*\*|/* This file is part of the coreboot project. */\n/*|' # ...filelist...
