roc-rk3399-pc has some specific requirements to support LEDS, environment. board detection and etc prior to U-Boot proper. So as of now SPL would be a better stage for these custom board requirements to support unlike TPL. Adding few of these custom requirements like LEDS in TPL would require extra code pulling and also the size of TPL can grow. So, this patch moves the leds code from TPL into SPL Board init led_setup code.
