irqchip/mmp: Mask off interrupts from other cores On mmp3, there's an extra set of ICU registers (ICU2) that handle interrupts on the extra cores. When masking off interrupts on MP1, these should be masked as well. We add a new interrupt controller via device tree to identify when we're looking at an mmp3 machine via compatible field of "marvell,mmp3-intc".
