target-i386/kvm: Hyper-V HV_X64_MSR_RESET support
HV_X64_MSR_RESET msr is used by Hyper-V based Windows guest
to reset guest VM by hypervisor. This msr is stateless so
no migration/fetch/update is required.
This code checks cpu option "hv-reset" and support by
kernel. If both conditions are met appropriate Hyper-V features
cpuid bit is set.
