2021-09-29nubus: add support for slot IRQsMark Cave-Ayland
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.

2021-09-29nubus-bridge: embed the NubusBus object directly within nubus-bridgeMark Cave-Ayland
Since nubus-bridge is a container for NubusBus then it should be embedded directly within the bridge device using qbus_create_inplace().

2021-09-29nubus: move NubusBus from mac-nubus-bridge to nubus-bridgeMark Cave-Ayland
Now that Nubus has its own address space rather than mapping directly into the system bus, move the Nubus reference from MacNubusBridge to NubusBridge.

2021-09-29mac-nubus-bridge: rename MacNubusState to MacNubusBridgeMark Cave-Ayland
This better reflects that the mac-nubus-bridge device is derived from the nubus-bridge device, and that the structure represents the state of the bridge device and not the Nubus itself. Also update the comment in the file header to reflect that mac-nubus-bridge is specific to the Macintosh.

2021-09-29nubus: move nubus to its own 32-bit address spaceMark Cave-Ayland
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.

2021-09-29nubus-device: remove nubus_register_rom() and nubus_register_format_block()Mark Cave-Ayland
Since there is no need to generate a dummy declaration ROM, remove both nubus_register_rom() and nubus_register_format_block(). These will shortly be replaced with a mechanism to optionally load a declaration ROM from disk to allow real images to be used within QEMU.

2021-09-29nubus: use bitmap to manage available slotsMark Cave-Ayland
Convert nubus_device_realize() to use a bitmap to manage available slots to allow for future Nubus devices to be plugged into arbitrary slots from the command line using a new qdev "slot" parameter for nubus devices. Update mac_nubus_bridge_init() to only allow slots 0x9 to 0xe on Macintosh machines as documented in "Designing Cards and Drivers for the Macintosh Family".

2021-09-29nubus-device: expose separate super slot memory regionMark Cave-Ayland
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.
