qemu: support xen hvm direct kernel boot
qemu side patch to support xen HVM direct kernel boot: if -kernel exists, calls xen_load_linux(), which will read kernel/initrd and add a linuxboot.bin or multiboot.bin option rom. The linuxboot.bin/multiboot.bin will load kernel/initrd and jump to execute kernel directly. It's working when xen uses seabios. During this work, found the 'kvmvapic' is in option_rom list, it should not be there in xen case. Set s->vapic_control = 0 in xen_apic_realize() to handle that.
