[PATCH] powerpc: EOI spurious irqs during boot so they can be reenabled later

> So when we receive a spurious irq, EOI it, and then mask it.

What happens when a new IRQ arrives on the interrupt controller
between these EOI and mask calls?  Should you instead first mask
it, and only then EOI it?  Or doesn't that work on XICS?
