Currently when using hvf we mishandle '-cpu max': we fall through to
the TCG version of its initfn, which then sets a lot of feature bits
that the real host CPU doesn't have. The hvf accelerator code then
exposes these bogus ID register values to the guest because it
doesn't check that the host really has the features.
Make '-cpu host' be like '-cpu max' for hvf, as we do with kvm.
