Cleanup/license headers (#1322)

* Attach missing licenses

Attached missing licenses to files that were missing the license
header.

* Apache license additions

Files in examples/lock-app/efr32/ must carry Apache license or a
suitable open source license.

Files in src/app/gen/gen/* are generated; attaching the copyright
notice to those files to satisfy the linter.
