Ah, v3 - oversaw this "minor" detail. Too bad that there is still no
GICv3 silicon in our hands that we could test against (do you know some
recommendable board?). I'm pretty sure Jailhouse's GICv3 support is
broken by now (due to lacking tests), plus it is not yet enabled for our
ARM64 port. But I'm a bit reluctant to enable this only over QEMU...
