    ARM: new VGIC: Provide system register emulation stub
    The Xen arch code traps system registers writes from the guest and will
    relay anything GIC related to the VGIC.
    Since this affects only GICv3 (which we don't yet emulate), provide a
    stub implementation of vgic_emulate() for now.
