target/arm/kvm: gic: Prevent creating userspace GICv3 with KVM
KVM doesn't support emulating a GICv3 in userspace, only GICv2. We
currently attempt this anyway, and as a result a KVM guest doesn't
receive interrupts and the user is left wondering why. Report an error
to the user if this particular combination is requested.
