option, now the code using the 802.15.4 driver directly must callieee802154_receive_handle_done

Known Issues
- For ESP32-P4, under the dual-core PD_TOP sleep scenario, if the sleep request is rejected, it may lead to a system deadlock triggering the watchdog.
- For ESP32-P4, RTC peripheral power domain cannot be powered down, resulting in ~20uA more power consumption.
- For ESP32-P4, there is a probability that the watchdog will be triggered due to the mpll being disabled and the L2 Cache not being able to write back when the PSRAM is enabled to sleep.
- For ESP32-P4, GPIO wake-up function and EXT1 wake-up function of GPIO8~15 are not available during deepsleep.
