x86/sev: Prevent GUEST_TSC_FREQ MSR interception for Secure TSC enabled guests
The hypervisor should not be intercepting GUEST_TSC_FREQ MSR(0xcOO10134)
when Secure TSC is enabled. A #VC exception will be generated otherwise. If
this should occur and Secure TSC is enabled, terminate guest execution.
