[PATCH 08/14] system/kvm: Expose kvm_irqchip_[add,remove]_change_notifier()

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Currently kvm_irqchip_add_irqfd_notifier() and
kvm_irqchip_remove_irqfd_notifier() are only declared on
target specific code. There is not particular reason to,
as their prototypes don't use anything target related.

Move their declaration with common prototypes, and
implement their stub.
