Associate the LED node name with the corresponding board silkscreen for
more precise identification. In fact, the board has a total of seven
LEDs, some of which are user-controllable (i. e. usr{1,2,3}), while
others are directly controlled by hardware (e. g. power, overcurrent,
...). All these LEDs are either green or red, so using the names
led-green and led-red for the two LEDs mapped in the DTS does not
simplify their identification on the board.
Moreover, this patch is a prerequisite for adding the usr3 LED, which
has not been included in the DTS.

As indicated by the board silkscreen, there are three user LEDs.
Add the missing one.

Series applied on stm32-next.
