treewide: Replace uses of "Nehalem"

The code in coreboot is actually for the Arrandale processors, which
are a MCM (Multi-Chip Module) with two different dies:

- Hillel:   32nm Westmere dual-core CPU
- Ironlake: 45nm northbridge with integrated graphics

This has nothing to do with the older, single-die Nehalem processors.
Therefore, replace the references to Nehalem with the correct names.
