[PATCH] KVM: x86: VMX: hyper-v: Enlightened MSR-Bitmap support

Enlightened MSR-Bitmap is a natural extension of Enlightened VMCS: Hyper-V Top Level Functional Specification states: "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 enlig
