x86: fix cpu MHz reporting for AMD family 0x11

Browse source 
Fix cpu MHz reporting for AMD family 0x11 when powernow-k8 is
disabled.

Just adhere to the CONSTANT_TSC feature bit for AMD CPUs when deciding
whether cpu_khz needs calibration. The additional check for CPU family
is not needed and prevents calibration for future CPUs.
