ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instances
commitb0ddb319db
upstream. The sh73a0 INTC can't mask interrupts properly most likely due to a hardware bug. Set the .control_parent flag to delegate masking to the parent interrupt controller, like was already done for irqpin1. Without this, accessing the three-axis digital accelerometer ADXL345 on kzm9g through /dev/input/event1 causes an interrupt storm, which requires a power-cycle to recover from. This was inspired by a patch for arch/arm/boot/dts/sh73a0.dtsi from Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>.
