configurations: Nisqually: use CCIN

Use the Nisqually CCIN (customer card identification number) instead of
the IM keyword from the system VPD.  The CCIN is a more direct FRU match
since it is associated with the Nisqually board only and not the chassis
in which it is installed (which is what the IM keyword signifies).
