irqchip/eznps: Acknowledge NPS_IPI before calling the handler
IPI_IRQ (also TIMER0_IRQ) should be acked before the action->handler is called
in handle_percpu_devid_irq.
The IPI irq is edge sensitive and we might miss an IPI interrupt if it is
triggered again while the handler runs.
Fixes: 44df427c894a ("irqchip: add nps Internal and external irqchips")
