[POWERPC] Add interrupt support for Marvell mv64x60 chips
There are 3 interrupt groups each with its own status/mask registers. We use a separate struct irq_chip for each interrupt group and handle interrupts in two stages or levels: level 1 selects the appropriate struct irq_chip, and level 2 selects individual interrupts within that irq_chip.
