Add irqchip driver for the ImgTec PowerDown Controller (PDC) as found in the TZ1090. The PDC has a number of general system wakeup (SysWake) interrupts (which would for example be connected to a power button or an external peripheral), and a number of peripheral interrupts which can also wake the system but are connected straight to specific low-power peripherals (such as RTC or Infrared). It has a single interrupt output for SysWakes, and individual interrupt outputs for each peripheral. The driver demuxes the SysWake interrupt line, and passes the peripheral interrupts straight through. It also handles the set_wake interrupt operation to enable/disable the appropriate wake event bits.
