[media] media: use media_gobj inside pads
PADs also need unique object IDs that won't conflict with
the entity object IDs.
The pad objects are currently created via media_entity_init()
and, once created, never change.
While this will likely change in the future in order to
support dynamic changes, for now we'll keep PADs as arrays
and initialize the media_gobj embedded structs when
registering the entity.
