ARM: shmobile: irqpin: add a DT property to enable masking on parent
To disable spurious interrupts, that get triggered on certain hardware, the irqpin driver masks them on the parent interrupt controller. To specify such broken devices a .control_parent parameter can be provided in the platform data. In the DT case we need a property, to do the same.
