[PATCH] qemu_validate: Only allow none address for watchdog ib700



Since QEMU 1.5.3, the ib700 watchdog device has no options for address,
and not address in device tree:

$ /usr/libexec/qemu-kvm -version
QEMU emulator version 1.5.3 (qemu-kvm-1.5.3-175.el7), Copyright (c) 2003-2008 Fabrice Bellard
$ /usr/libexec/qemu-kvm -device ib700,\?
$ virsh qemu-monitor-command seabios --hmp info qtree|grep ib700 -A 2
        dev: ib700, id "watchdog0"
        dev: isa-serial, id "serial0"
          index = 0

So only allow it to use none address.
