Convert nubus_device_realize() to use a bitmap to manage available slots to allow for future Nubus devices to be plugged into arbitrary slots from the command line using a new qdev "slot" parameter for nubus devices. Update mac_nubus_bridge_init() to only allow slots 0x9 to 0xe on Macintosh machines as documented in "Designing Cards and Drivers for the Macintosh Family".
