Antonio Borneo d8042fbb46 contrib: replace the BSD-3-Clause license tag
Replace the BSD-3-Clause boilerplate with the SPDX tag.
Add the SPDX tag and the copyright to two makefiles that were
added by TI with the other files in their respective folder.

The SPDX tag on files *.c is incorrect, as it should use the C99
single line comment using '//'. But current checkpatch doesn't
allow C99 comments, so keep using standard C comments, by now.
