I also work on this, just not published yet. Some notes about your version:
1. May be there should be hw/intc/arm_gicv3_kvm.c file created for GICv3? As
far as i can
see, save/restore code should differ a lot.
2. kvm_arch_irqchip_create() should probe only for type we want to get. It has
to be
passed there somehow from the virt machine initializer. And, if we want GICv3,
then upon
failure it should return error, not zero. This is because when
kvm_arch_irqchip_create()
returns zero, a fallback code is used, which will create GICv2.
3. Perhaps you should base your work on these patch sets:

I added Shlomo to cc because he might also be interested.
