Wu Zhou 8af2c263db hv: disable HFI and ITD for guests 
The Hardware Feedback Interface (HFI) and Intel® Thread Director (ITD)
features require OS to provide a physical page address to
IA32_HW_FEEDBACK_PTR. Then the hardware will update the processor
information to the page address. The issue is that guest VM will program
its GPA to that MSR, causing great risk of tempering memory.

So HFI and ITD should be made invisible to guests, until we provide
proper virtulization of those features.
