ati-vga: Implement dummy VBlank IRQ
The MacOS driver exits if the card does not have an interrupt. If we
set PCI_INTERRUPT_PIN to 1 then it enables VBlank interrupts and it
boots but the mouse pointer cannot be moved. This patch implements a
dummy VBlank interrupt triggered by a 60 Hz timer. With this the
pointer now moves but MacOS still hangs somewhere before completely
finishing boot.
