DRM connectors have two properties, "enabled" and "status", standing for "enabled by userspace" and "a display has been connected". Connector status cannot be reliably detected sometimes, in this case status will be set to unknown and it is still okay to enable it. Some drivers are also able to enable disconnected connectors. So it is both meaningful to detect connectors in two states, - An enabled connector, where it must have been operating in some configuration required by userspace - A connected connector, where driver is sure a display has been connected to the port, this is the obvious case. In the original implementation, only information of connected connectors are detected and an enabled connector without hotplug detection capability, like a Composite video connector, will be silently ignored. Switch to the new strategy to detect these connectors correctly.
