Now, that the driver implements the common DRM panel API
the unbind no longer needs to be suppressed.

I'd be curious to know what happens when you try to unbind through sysfs
though...

I'm sure it crashes. The same happens if you unload the modules in wrong order (unload panel first,
then omapdrm). I haven't looked at this yet, it's low priority issue...
