You need to ensure that the set IO can be configured as a GPIO wake-up source,
refer SOC_GPIO_HP_PERIPH_PD_SLEEP_WAKEABLE_MASK in soc_caps.h.

This option set the gpio wake-up trigger signal, In deep sleep, only high or low level wake-up is
supported. If this option is enabled, it is a high level wake up, otherwise it is a low level wake up.
Selects esp_sleep_gpio_wake_up_mode_t for
esp_sleep_enable_gpio_wakeup_on_hp_periph_powerdown.
Edge choices require SOC_RTC_GPIO_EDGE_WAKEUP_SUPPORTED on the target.
