* @brief Enable wakeup from light sleep using GPIOs
*
* Each GPIO supports wakeup function, which can be triggered on either low level
* or high level. Unlike EXT0 and EXT1 wakeup sources, this method can be used
* both for all IOs: RTC IOs and digital IOs. It can only be used to wakeup from
* or high level. This method can be used with any IO (RTC or digital), whereas
* external RTC wakeup is limited to RTC GPIOs. It can only be used to wakeup from
* light sleep though.
*
* To enable wakeup, first call gpio_wakeup_enable, specifying gpio number and
