nb/intel/nehalem: Rename to ironlake

The code is for Arrandale CPUs, whose System Agent is Ironlake.

This change simply replaces `nehalem` with `ironlake` and `NEHALEM`
with `IRONLAKE`. The remaining `Nehalem` cases are handled later, as
changing some of them would impact the resulting binary.

Tested with BUILD_TIMELESS=1 without adding the configuration options
into the binary, and packardbell/ms2290 does not change.
