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...
