hw/nubus: add nubus-virtio-mmio device

Browse source 
The nubus-virtio-mmio device is a Nubus card that contains a set of 32 virtio-mmio
devices and a goldfish PIC similar to the m68k virt machine that can be plugged
into the m68k q800 machine.

There are currently a number of drivers under development that can be used in
conjunction with this device to provide accelerated and/or additional hypervisor
services to 68k Classic MacOS.
