Add support for the irq controller in Qualcomm 8xxx pmic. The 8xxx interrupt controller provides control for gpio and mpp configured as interrupts in addition to other subdevice interrupts. The interrupt controller also provides a way to read the real time status of an interrupt. This real time status is the only way one can get the input values of gpio and mpp lines.
