arm_kvm: Do not assume particular GIC type in kvm_arch_irqchip_create()
This allows us to use different GIC types from v2. There are no kernels which could advertise KVM_CAP_DEVICE_CTRL without the actual ability to create GIC with it. GIC version probe code moved to kvm_arm_vgic_probe() which will be used later.
