nubus-device: expose separate super slot memory region
According to "Designing Cards and Drivers for the Macintosh Family" each physical
nubus slot can access 2 separate address ranges: a super slot memory region which
is 256MB and a standard slot memory region which is 16MB.
Currently a Nubus device uses the physical slot number to determine whether it is
using a standard slot memory region or a super slot memory region rather than
exposing both memory regions for use as required.
