Sure I can remove them ... just found them in the irqs.h file and thought it
made sense to add them. I'll just cut them.

Since there is actually an internal IRQ controller in the host controller
cascading the four PCI child IRQs that we model as an irqchip, I don't
really see why they have these "PCI B-D" IRQs... anyone has a guess?
