The INTEL_FAM6 list has become a mess again. Try and bring some sanity
back into it.
Where previously we had one microarch per year and a number of SKUs
within that, this no longer seems to be the case. We now get dfferent
uarch names that share a 'core' design.
Add the core name starting at skylake and reorder to keep the cores in
chronological order. Furthermore, Intel marketed the names {Amber,
Coffee, Whiskey} Lake, but those are in fact steppings of Kaby Lake, add
comments for them.

Soon it'll be all an unrecognizable mess with IP blocks tetris. :-)

x86/cpu: Resort and comment Intel models
The INTEL_FAM6 list has become a mess again. Try and bring some sanity
back into it.
Where previously we had one microarch per year and a number of SKUs
within that, this no longer seems to be the case. We now get different
uarch names that share a 'core' design.
Add the core name starting at skylake and reorder to keep the cores
in chronological order. Furthermore, Intel marketed the names {Amber,
Coffee, Whiskey} Lake, but those are in fact steppings of Kaby Lake, add
comments for them.
