Well, I basically did `s/nehalem/ironlake/g` and `s/NEHALEM/IRONLAKE/g` under src/. It was the simplest way to rename a bunch of instances without affecting prints.

Also, the CPU and the SA are always connected together. Sure, the "Ironlake" name under src/cpu/ might be weird, but it is more correct than Nehalem.

With regard to `IRONLAKE_BCLK`, it is indeed related to the SA: it is the only BCLK it supports. Moreover, I would say that "HILLEL_BCLK" is too obscure (Hillel is the name of the 32nm CPU die), and CLARKDALE_ARRANDALE_BCLK` is just obnoxiously long. Therefore, I would prefer that bikeshedding be left out of this change.
