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.
