x86: Print the hypervisor returned tsc_khz during boot
On an AMD-64 system the processor frequency that is printed during
system boot, may be different than the tsc frequency that was
returned by the hypervisor, due to the value returned from
calibrate_cpu.
For debugging timekeeping or other related issues it might be
better to get the tsc_khz value returned by the hypervisor.
The patch below now prints the tsc frequency that the VMware
hypervisor returned.
