Bas Nieuwenhuizen 301b1d3a91 tools/power/turbostat: Fix turbostat for AMD Zen CPUs ... It was reported that on Zen+ system turbostat started exiting, which was tracked down to the MSR_PKG_ENERGY_STAT read failing because offset_to_idx wasn't returning a non-negative index. This patch combined the modification from Bingsong Si and Bas Nieuwenhuizen and addd the MSR to the index system as alternative for MSR_PKG_ENERGY_STATUS.
