commit d1fb034 upstream. Pantherlake is a mobile CPU. Diamond Rapids next generation Xeon. Intel-SIG: commit d1fb034 x86/cpu: Add two Intel CPU model numbers.

commit 70d1d98934e723b9e463283a542b88f4f009ae82 upstream. This model was added as INTEL_PANTHERCOVE_X (based on the name of the core) with a comment that the platform name is Diamond Rapids. It was also placed at the end of the file in a new section for family 19 processors. This is different from previous naming as Andrew Cooper noted. PeterZ agreed and posted a patch[1] to fix the name and move it in sequence with other Xeon servers. But without a commit description or sign-off the patch wasn't ever applied. Patch updated to cover one additional use of the #define by turbostat and to change the "Family 6" comment to also list 18 and 19 since new models in these families are mixed in with family 6.
