Abondon the concept of resources under a link

Resources under a link are tied to resources under both ends of the link, and resources under a port are thought to be first-class objects compared to concept of link resources. We will deal with only device related resources from now on. Change-Id: I6aa418d1bf64b28374f325db0bc7e393f770dcdd
