[PATCH v3 1/9] led: turn LED ON on initial SW blink

[Christian Marangi]

We currently init the LED OFF when SW blink is triggered when
on_state_change() is called. This can be problematic for very short
period as the ON/OFF blink might never trigger.

Turn LED ON on initial SW blink to handle this corner case and better
display a LED blink from the user.
