src/mb: Update unlicensable files with the CC-PDDC SPDX ID

These files contain no creative content, and therefore have no
copyright. This effectively means that they are in the public
domain.

This commit updates the unlicensable empty (and effectively empty)
files with the CC-PDDX identifier for license compliance scanning.
