97b1f5aa15 irqchip/irq-csky-mpintc: Support auto irq deliver to all cpus 
[ Upstream commit db56c5128e ]

The csky,mpintc could deliver a external irq to one cpu or all cpus, but
it couldn't deliver a external irq to a group of cpus with cpu_mask. So
we only use auto deliver mode when affinity mask_val is equal to
cpu_present_mask.

There is no limitation for only two cpus in SMP system.
