Most DAPM input and output pins of the wm9712 are either used in the card's DAPM routing table or are marked as not connected. The only two exception are "PHONE" and "PCBEEP" input, lets assume that those were simply overlooked and that the routing table is complete. Set the fully_routed flag of the card instead of manually marking the unused inputs and outputs as not connected. This makes the code a bit shorter and cleaner.
