The arm_gic_kvm now calls kvm_irqchip_set_qemuirq_gsi to build
the hash table storing qemu_irq/gsi mappings. From that point on
irqfd can be setup directly from the qemu_irq using
kvm_irqchip_add_irqfd_notifier.

v16 -> v17:
- add Paolo's A-b

v15 -> v16:
- added Vikram's T-b
- Resolve rebase conflict

v2 -> v3:
- kvm_irqchip_add_qemuirq_irqfd_notifier renamed into
  kvm_irqchip_add_irqfd_notifier
