irqchip: Add NXP INTMUX interrupt multiplexer support
The Interrupt Multiplexer (INTMUX) expands the number of peripherals that can interrupt the core: * The INTMUX has 8 channels that are assigned to 8 NVIC interrupt slots. * Each INTMUX channel can receive up to 32 interrupt sources and has 1 interrupt output. * The INTMUX routes the interrupt sources to the interrupt outputs.
