Introduce EXT1 wakeup functionality to the ESP32-S3 power management subsystem. With this feature, the ESP32-S3 can wake up from PM_STANDBY or PM_SLEEP when one or more RTC GPIOs trigger the EXT1 condition. Changes include: - Added EXT1 wakeup configuration and preparation logic in rtc code. - Integrated EXT1 handling in pmstandby() and pmsleep(). - New board-level Kconfig options under ESP32-S3 DevKit menu: - CONFIG_PM_EXT1_WAKEUP: enable EXT1 wakeup support - CONFIG_PM_EXT1_WAKEUP_RTC_GPIO<n>: select RTC GPIOs as wake sources - CONFIG_PM_EXT1_WAKEUP_TRIGGER_MODE: choose wakeup on HIGH or LOW level - Fixing Kconfig style - Fixing comments standard - Adding PM documentation for esp32s3-devkit Impact: - No build impact unless CONFIG_PM_EXT1_WAKEUP is enabled. - When enabled, ESP32-S3 can wake from low-power states via RTC GPIOs. - No new public API introduced; controlled via board Kconfig. Tested on ESP32-S3 DevKit: - Configured GPIO4 and GPIO5 as EXT1 wake sources. - Verified wakeup from light sleep and deep sleep on external signals. - Wakeup reason correctly reported as EXT1.
