[PATCH V3 2/3] Documentation: dt-bindings: mfd: palmas: document optional wakeup IRQ

With the recent pinctrl-single changes, SoCs such as OMAP family can treat wake-up events from deeper low power states as interrupts. This is usable when the wakeup from deeper low power states is triggered by a different hardware mechanism tied to pinctrl compared to the routine interrupt
