As the next bridge is often/always a connector the call had no effect anyway. So drop it. From the git history I could see this call was included in the original version of the driver so there was no help there to find out why it was added in the first place. But a lot has changed since the initial driver were added and is seems safe to remove the call now.

Likewise update enable/disable to their atomic variants. With these changes omapdrm now implement the full bridge atomic API.
