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.
