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(). Signed-off-by: Noam Camus <[email protected]> Signed-off-by: Vineet Gupta <[email protected]>
