[PATCH 6/7] KVM: SVM: hyper-v: Enlightened MSR-Bitmap support

Enlightened MSR-Bitmap as per TLFS: "The L1 hypervisor may collaborate with the L0 hypervisor to make MSR accesses more efficient. It can enable enlightened MSR bitmaps by setting the corresponding field in the enlightened VMCS to 1. When enabled, L0 hypervisor does not monitor the MSR
