KVM: Distangle eventfd code from irqchip
The current eventfd code assumes that when we have eventfd, we also have irqfd for in-kernel interrupt delivery. This is not necessarily true. On PPC we don't have an in-kernel irqchip yet, but we can still support easily support eventfd. Signed-off-by: Alexander Graf <agraf@suse.de>
