This updates the Linux header to version 4.0-rc2.
Besides virtio_config.h now sets VIRTIO_TRANSPORT_F_END to 33.
Use the same value in duplicate definition located in
include/hw/virtio/virtio.h.

This patch forces vgic initialization in the vgic realize function.
It uses a new group/attribute that allows such operation:
KVM_DEV_ARM_VGIC_GRP_CTRL/KVM_DEV_ARM_VGIC_CTRL_INIT
This earlier initialization allows, for example, to setup VFIO
signaling and irqfd after vgic initialization, on a reset notifier.
