leds: leds-st1202: Fix NULL pointer access on race condition
st1202_dt_init() calls devm_led_classdev_register_ext() before the internal data structures are properly set up, so the LEDs become visible to user space while being partially initialized, leading to a window where trying to access them causes a NULL pointer access. Move devm_led_classdev_register_ext() from DT initialization to the end of the probe function when DT and hardware are fully initialized and ready to interact with user space.
