The cortex-a15 is not present anymore when CONFIG_TCG=n, so use the

Our recommendation currently for KVM on ARM is to always use CPU="host", as
named cpu models generally don't work (yet?) with KVM.

Should then "host" be the default for KVM if CONFIG_TCG=N or CONFIG_TCG=M and
the TCG .so is not loaded?
Yes, "host" seems to make more sense. I was under the impression that
there was a way to use cortex-a57 and cortex-a53 since they have
cpu->kvm_target set.
One may use a -cpu other than 'host' if and only if it exactly matches the host.
