[ Upstream commit 4184f0190792aea06553af963741a24cc9b47689 ]
The Radxa Cubie A5E has a 3-color LED. The green and blue LEDs are wired to GPIO pins on the SoC, and the green one is lit by default to serve as a power indicator. The red LED is wired to the M.2 slot.
Add device nodes for the green and blue LEDs.
A default "heartbeat" trigger is set for the green power LED, though in practice it might be better if it were inverted, i.e. lit most of the time.
