tools/power turbostat: AMD: msr offset 0x611 read failed: Input/output error
Turbostat exits during RAPL probe with:
turbostat: cpu0: msr offset 0x611 read failed: Input/output error
A binary with this bug can be used successfully with
the option "--no-msr"
Fix this regression by trusting the static AMD RAPL MSR offset.
