q800: wire macfb IRQ to separate video interrupt on VIA2
Whilst the in-built Quadra 800 framebuffer exists within the Nubus address
space for slot 9, it has its own dedicated interrupt on VIA2. Force the
macfb device to occupy slot 9 in the q800 machine and wire its IRQ to the
separate video interrupt since this is what is expected by the MacOS
interrupt handler.
