ARC: [plat-eznps] remove IPI clear from SMP operations
Today we register to plat_smp_ops.clear() method which actually is acking the IPI. However this is already taking care by our irqchip driver specifically by the irq_chip.irq_eoi() method. This is perfect timing where it should be done and no special handling is needed at plat_smp_ops.clear().
