Added a stepping enum to k8.h. This will allow us to do things like this:
if (cpu_stepping(node) < E0)

and so on instead of is_cpu_pre_e0_in_bsp or whatever it is. 

Added and fixed Kconfig variables. 

Broke out northbridge by function, so we can see what goes with what. 

This tree still builds a working DBE62 coreboot that boots a kernel; no harm done to existing ports.
