2016-05-09irqchip: add nps Internal and external irqchipsNoam Camus
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.
