Dhananjay Ugwekar a3c944359f tools/power/cpupower: Fix Pstate frequency reporting on AMD Family 1Ah CPUs ...

[ Upstream commit 43cad521c6 ]

Update cpupower's P-State frequency calculation and reporting with AMD
Family 1Ah+ processors, when using the acpi-cpufreq driver. This is due
to a change in the PStateDef MSR layout in AMD Family 1Ah+.

Tested on 4th and 5th Gen AMD EPYC system
