media: mc-entity: Add a new helper function to get a remote pad for a pad
The newly added media_entity_remote_source_pad_unique() helper function handles use cases where the entity has a link enabled uniqueness constraint covering all pads. There are use cases where the constraint covers a specific pad only. Add a new media_pad_remote_pad_unique() function to handle this. It operates as media_entity_remote_source_pad_unique(), but on a given pad instead of on the entity.
