hw/intc/arm_gicv3: Add has-nmi property to GICv3 device

Browse source 
Add a property has-nmi to the GICv3 device, and use this to set
the NMI bit in the GICD_TYPER register. This isn't visible to
guests yet because the property defaults to false and we won't
set it in the board code until we've landed all of the changes
needed to implement FEAT_GICV3_NMI.
