staging: vc04_services: add proper SPDX identifier for dual licensed files

There are a number of vc04_services files that are dual licensed under
the GPL2 and BSD-3 licenses.  They currently do not have a SPDX
identifier on them, so fix that up and add the proper identifier so that
tools can pick it up easily.
