hw/intc/arm_gic: Initialize the vgic in the realize function
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.
