Now that all of the Property arrays are counted, we can remove
the terminator object from each array. Update the assertions
in device_class_set_props to match.
With struct Property being 88 bytes, this was a rather large
form of terminator. Saves 30k from qemu-system-aarch64.

Rename qbus_create_inplace() to qbus_init(); this is more in line
with our usual naming convention for functions that in-place
initialize objects.

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.

This is to allow Macintosh machines to further specify which slots are available
since the number of addressable slots may not match the number of physical slots
present in the machine.

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.

This is to allow the Nubus bridge to store its own additional state. Also update
the comment in the file header to reflect that nubus-bridge is not specific to
the Macintosh.
