KVM: arm/arm64: vgic-new: vgic_init: implement kvm_vgic_hyp_init
Implements kvm_vgic_hyp_init and vgic_probe function. This uses the new firmware independent VGIC probing to support both ACPI and DT based systems (code from Marc Zyngier). The vgic_global struct is enriched with new fields populated by those functions.
