irqchip/meson: Add support for gpio interrupt controller

Add support for the interrupt gpio controller found on Amlogic's meson SoC family. This controller is a separate controller from the gpio controller. It is able to spy on the SoC pad. It is essentially a 256 to 8 router with a filtering block to select level or edge and polarity. The number of actual mappable inputs depends on the SoC.
