Len Brown 19476a592b tools/power turbostat: Validate RAPL MSRs for AWS Nitro Hypervisor
Even though the platform->plat_rapl_msrs enumeration may be accurate,
a VM, such as AWS Nitro Hypervisor, may deny access to the underlying MSRs.

Probe if PKG_ENERGY is readable and non-zero.
If no, ignore all RAPL MSRs.
