The Avaota A1 board features 4 RGB LEDs in a string connected to the
SoC's LED controller.

Enable the LED controller and add device nodes for them. The timings
were copied from the downstream vendor DTS. The design does not specify
what these LEDs are for, nor are there any markings on the board for
them, so just use them as indicators.
