Lucas De Marchi b5a2cd070d Use SPDX header for license
Drop the lengthy license from each file and just use SPDX like most
projects nowadays. This doesn't have any change to license, just how
they are recorded in each file.

This follows the kernel approach: header files use '/*' for comments
while .c files use '//'. For .m4, use "#".
