eldrid: support ectool led control when no adapter
eldrid: support ectool led control when no adapter

The 'ectool' command was not able to set the
battery LED color.
When no AC adapter is connected, that battery
LED code temporarily turns of all LEDs until
the next HOST_TICK.
Bypass this check if the host has disabled LED
auto control.
