Adopt the SPDX license identifier headers to ease license compliance
management. All files in the driver are licensed under the GPLv2+ except

likely an oversight, but fixing this requires contacting the copyright
owners and is out of scope for this patch.
While at it fix the file descriptions to match file names where copy and
paste error occurred.
