inteltool: add initial support for Nehalem
Also, add pretty printing of Westmere's DMI registers (tested on my t410s by staring at non-zero output values :) Apparently Nehalem does not have a MEMBAR? But there are some documented memory controller control registers in PCI configuration space... left out for now. The PCIEXBAR is not documented publicly AFAICT, but there is a similar register on a device on bus 0xFF. phcoder might know more...
