nb/intel/ironlake: Add definition for QPI Link PCI device
On multi-socket platforms, there can be two QPI buses, each with its own
PCI device. We only have one QPI link on Arrandale, though. In case
support for multi-socket processors ever gets added, name it Link 0.
Tested with BUILD_TIMELESS=1, Packard Bell MS2290 does not change.
