nubus: use bitmap to manage available slots
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".
