Len Brown noticed something was amiss in our INTEL_FAM6_*
definitions. It seems like model 0x1F was a Nehalem part,
marketed as "Intel Core i7 and i5 Processors" (according to the
SDM). But, although it was a Nehalem 0x1F had some uncore events
which were shared with Westmere.
Len also mentioned he thought it was called "Havendale", which
Wikipedia says was graphics-oriented and canceled:
https://en.wikipedia.org/wiki/Nehalem_(microarchitecture)
So either way, it's probably not imporant what we call it, but
call it Nehalem to be accurate, and add a "G" since it seems
graphics-related. If it were canceled that would be a good reason
why it's so sparsely and inconsistently referred to in the code.

Problem:
We have a boatload of open-coded family-6 model numbers. Half of
them have these model numbers in hex and the other half in
decimal. This makes grepping for them tons of fun, if you were
to try.
Solution:
Consolidate all the magic numbers. Put all the definitions in
one header.
The names here are closely derived from the comments describing
the models from arch/x86/events/intel/core.c. We could easily
make them shorter by doing things like s/SANDYBRIDGE/SNB/, but
they seemed fine even with the longer versions to me.
Do not take any of these names too literally, like "DESKTOP"
or "MOBILE". These are all colloquial names and not precise
descriptions of everywhere a given model will show up.
