Since ivybridge is synonymous with GEN7, we have been going with the
latter. I want to reserve the capability bits for instances where we
either have a workaround for a few chipsets (and so I have a patch to
strip out the is_broadwater and is_crestline since they are just a single
pci-id each) or otherwise describing a feature across chipsets. 

So I think we just want IS_GEN7() for IVB code.
