This left the driver with an undocumented (and wrong) DT parsing logic, so lets get rid of this code as well until the input connectors support is implemented properly. It's a partial revert due other patches added on top of mentioned commit not allowing the commit to be reverted cleanly anymore. But all the code related to the DT parsing logic and input entities creation are removed.
