The MEDIA_PAD_FL_MUST_CONNECT flag indicates that the pad requires an enabled link to stream, but only if it has any link at all. This makes little sense, as if a pad is part of a pipeline, there are very few use cases for an active link to be mandatory only if links exist at all. A review of in-tree drivers confirms they all need an enabled link for pads marked with the MEDIA_PAD_FL_MUST_CONNECT flag. Expand the scope of the flag by rejecting pads that have no links at all. This requires modifying the pipeline build code to add those pads to the pipeline.
