xend: Use AUTO_PHP_SLOT_STR=0xff rather than 0x0 for auto pci allocation
Rather than use "0x0" to signify that the hotplug slot should
be automatically selected by qemu-dm, define AUTO_PHP_SLOT_STR.
At the same time, change the magic value form 0x0 to 0xff,
in line with changes made to qemu-dm to allow any unused PCI
device to be used for hotplug.
