This just initializes the basic Xen support in KVM for now. Only permitted on TYPE_PC_MACHINE because that's where the sysbus devices for Xen heap overlay, event channel, grant tables and other stuff will exist. There's no point having the basic hypercall support if nothing else works. Provide sysemu/kvm_xen.h and a kvm_xen_get_caps() which will be used later by support devices.
