Commit 6dac1195181c ("KVM: selftests: Make Hyper-V tests explicitly require
KVM Hyper-V support") wrongfully added KVM_CAP_HYPERV_DIRECT_TLBFLUSH
requirement to hyperv_evmcs/hyperv_svm_test tests. The capability is only set
when KVM runs on top of Hyper-V. The result is that both tests just skip when
launched on bare metal. Add the required infrastructure and check for the
correct CPUID bit in KVM_GET_SUPPORTED_HV_CPUID instead.
