Subject: [PATCH] x86/cpu: Add Sapphire Rapids CPU model number

Latest edition (039) of "Intel Architecture Instruction Set Extensions
and Future Features Programming Reference" includes three new CPU model
numbers. Linux already has the two Ice Lake server ones. Add the new
model number for Sapphire Rapids.

I'd appreciate this being merged to Linus, even though it wasn't posted
before the merge window opened. It will avoid it being a dependency for
other patch series (perf, edac, ...)

FYI: ISE039 is here today (not included in commit message because the URL
isn't long term stable).
