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.

As far as linux reboot is concerned, once reboot is done, there is no led status 
indication when in u-boot. Since its a reboot and board has entered full 
power mode, enabling RED led would be fine I guess.
