arm64: dts: allwinner: a527: cubie-a5e: Add LEDs
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.
