Some irqchip initialization must be done on secondary CPUs. On mvebu platforms, this is currently achieved by having the arch/arm/mach-mvebu/platsmp.c code directly call into a function exported by the irqchip driver, which isn't really nice. This commit changes this by using the same solution as the one used in the GIC driver: the irqchip driver registers a CPU notifier, which is used to do the secondary CPU IRQ initialization. This way, the irqchip driver is completely autonomous, and the function no longer needs to be exposed from the irqchip driver to the SoC code.
