Some files add a comment giving the path of the file inside the Linux tree, which is pretty useless since the reader had to find the file to open it. Getting rid of these comments will also allow us to easily move these files around when needed. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
