[RESEND PATCH 1/3] x86/vmware: Use tsc_khz value for calibrate_cpu()
After aa297292d708, there are separate native calibrations for cpu_khz and
tsc_khz. The code sets x86_platform.calibrate_cpu to native_calibrate_cpu()
which looks in cpuid leaf 0x16 or msrs for the cpu frequency. Since we keep
the tsc_khz constant (even after vmotion), the cpu_khz and tsc_khz may
start diverging.
tsc_init() now does
cpu_khz = x86_platform.calibrate_cpu();
