Before this commit such systems would not wake up when opening the lid, requiring the powerbutton to be pressed after opening the lid to wakeup. This commit calls enable_irq_wake() for _IAE GpioInts with a valid event handler which have their Wake flag set. This fixes such systems not waking up when opening the lid.
