mvebu: macchiatobin-singleshot: enable heartbeat LED
With board revision 1.3, SolidRun moved the power LED to the middle of
the board. In old place of power LED a GPIO controllable heartbeat LED
was added. This commit touches only Single Shot variant, because all
have revision 1.3. Some boards could be placed in an enclosure, therefore
the LED18 is enabled by default, since that'll be the only visible
indicator that the board is operating.
