[PATCH 2/5] roc-rk3399-pc: Configure the leds only during POR

[Jagan Teki <jagan@amarulasolutions.com>]

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.
