This device is a clone of Odroid Go Advance, with added PWM motor, internal
gamepad connected on USB instead of just having it be on GPIO + ADC, and
missing battery shunt resistor.

There's also an LED on GPIO 77(I *guess* PB5 on &gpio2), that is controlled in a weird way:

- It is set to red by setting output value to 1
- Set to green by setting output value to 0
- Set to yellow by setting gpio direction to input

I have no idea how to describe that in DTS, without adding a custom
driver, for now it's just left out.
