Subject: hwmon: (k10temp) Define SVI telemetry and current factors for Zen2 CPUs
Git-commit: d6144a40041a70ecce410a07d3a2b6906f6e7da9
Patch-mainline: v5.10
References: jsc#SLE-17823 jsc#SLE-23139 jsc#ECO-3666

The voltage telemetry registers for Zen2 are different from Zen1. Also
the factors of CPU current values are changed on Zen2. Add new definitions
for these register.
