ROC-RK3399-PC has specific set of configurations for on-board led setup.
Due to easiness for user to know the state of the board roc-rk339-pc board code will setup the led on/off, and waiting for user to press power key.
All this needs to happen only during power-on-reset not for soft reset or WDT. So add reset cause check to POR and configure leds.
