Subject: [PATCH] x86/cpu: Add new Alderlake and Raptorlake CPU model numbers

Intel is subdividing the mobile segment with additional models
with the same codename. Using the Intel "N" and "P" suffices
for these will be less confusing than trying to map to some
different naming convention.

I think the earlier patch for Alderlake "N" got stuck in limbo
trying to resolve whether we should add the "_N" suffix to our list
of acceptable CPU model #define names. Now we have another one "_P".

Can we just take these, and move on?
