pc_machine_kvm_type() was introduced by commite21be724ea("i386/xen: add pc_machine_kvm_type to initialize XEN_EMULATE mode") to do Xen specific initialization by utilizing kvm_type method. commiteeedfe6c63("hw/xen: Simplify emulated Xen platform init") moves the Xen specific initialization to pc_basic_device_init(). There is no need to keep the PC specific kvm_type() implementation anymore. So we'll fallback to kvm_arch_get_default_type(), which simply returns 0.
