initialize objects.

nubus: add support for slot IRQs
...
Each Nubus slot has an IRQ line that can be used to request service from the
CPU. Connect the IRQs to the Nubus bridge so that they can be wired up using qdev
gpios accordingly, and introduce a new nubus_set_irq() function that can be used
by Nubus devices to control the slot IRQ.

nubus-bridge: embed the NubusBus object directly within nubus-bridge
...
Since nubus-bridge is a container for NubusBus then it should be embedded
directly within the bridge device using qbus_create_inplace().

...
Now that Nubus has its own address space rather than mapping directly into the
system bus, move the Nubus reference from MacNubusBridge to NubusBridge.
