arm: vgic device control api support
Support creating the ARM vgic device through the device control API and setting the base address for the distributor and cpu interfaces in KVM VMs using this API. Because the older KVM_CREATE_IRQCHIP interface needs the irq chip to be created prior to creating the VCPUs, we first test if we can use the device control API in kvm_arch_irqchip_create (using the test flag from the device control API). If we cannot, it means we have to fall back to KVM_CREATE_IRQCHIP and use the older ioctl at this point in time. If however, we can use the device control API, we don't do anything and wait until the arm_gic_kvm driver initializes and let that use the device control API.
