mac-nubus-bridge: rename MacNubusState to MacNubusBridge

This better reflects that the mac-nubus-bridge device is derived from the
nubus-bridge device, and that the structure represents the state of the bridge
device and not the Nubus itself. Also update the comment in the file header to
reflect that mac-nubus-bridge is specific to the Macintosh.

nubus: move nubus to its own 32-bit address space

According to "Designing Cards and Drivers for the Macintosh Family" the Nubus
has its own 32-bit address space based upon physical slot addressing.

Move Nubus to its own 32-bit address space and then use memory region aliases
to map available slot and super slot ranges into the q800 system address
space via the Macintosh Nubus bridge.

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".
