x86: fix cpu MHz reporting for AMD family 0x11

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.
