Separate drivers internal APIs from public APIs (#5)

* Move source files and internal headers to `internal` dir
* Amend test files and other modules include paths for internal headers
* Add Doxygen comments for documenting internal and public drivers APIs
* Remove incorrectly grouped Devicekey from the drivers Doxygen
  group and add to the newly created `Device Key` group.
