irqchip/eznps: Drop pointless static qualifier in nps400_of_init()

There is no need to have the 'struct irq_domain *nps400_root_domain'
variable static since new value is always assigned before use.

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.

irqchip: add nps Internal and external irqchips

Adding EZchip NPS400 support.
Internal interrupts are handled by Multi Thread Manager (MTM)
Once interrupt is serviced MTM is acked for deactivating the interrupt.
External interrupts are handled by MTM as well as at Global Interrupt
Controller (GIC) e.g. serial and network devices.
