In case of a power interruption, human intervention is required which is not desirable if the device is installed at a remote location. Drop yellow LED as it is not much of use. Keep red LED(diy-led) as it is, to indicate board in full power mode. Signed-off-by: Suniel Mahesh <sunil@amarulasolutions.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
