    hw/intc: declare GICv3 regions as little endian

    The GIC should always be a little-endian device as big-endian
    behaviour is a function of the current CPU configuration not the
    system as a whole. This should have no functional effect as the GIC
    cannot be instantiated on a BE system but will help the single binary
    efforts.
