Fallback to legacy system time logic when host does not have TSC_CONTROL
If the host doesn't have TSC scaling feature, then scaling down TSC to
the lowest value will fail, and we will fall back to legacy logic
anyway, but we leave an ugly log message in host's kernel log.
kernel: user requested TSC rate below hardware speed
Instead, check for KVM_CAP_TSC_CONTROL when initializing KVM, and fall
back to legacy logic early if host's cpu doesn't support that.
