I'd like some clarification about this.

My Pine64-LTS was a used unit personally given to me by TL Lim, which came
with LEDs that I assume were soldered on by hand as their mounting angles
are slightly off. My Pine64+ (the original from the Kickstarter campaign)
and SoPine baseboard (a new unit, also given to me by TL Lim) came without
LEDs soldered on.

I'm OK with adding the LED to the device tree. I'm just not sure about the
color.
