rG93ba7dce8954: arm64: Attach the vgic even if there is no ITS
rGc12d6cc326b7: arm64: Attach the vgic even if there is no ITS

Summary

If there is no ITS device so no memory resources the gicv3 driver would
exit attaching early. This caused the vgic driver to also not be
attached, even if it could.
