[media] media: v4l-core add enable/disable source common interfaces
Add a new interfaces to be used by v4l-core to invoke enable source and disable_source handlers in the media_device. The enable_source helper function invokes the enable_source handler to find media source entity connected to the entity and check is it is available or busy. If source is available, link is activated and pipeline is started. The disable_source helper function invokes the disable_source handler to deactivate and stop the pipeline.
