ARM: da850-lego-ev3: Add device tree node for sound
This adds a device tree node for sound on LEGO MINDSTORMS EV3. The EV3 uses one of the SoC PWMs connected to an amplifier to create sound from a speaker. The PWM is passed through a low-pass filter, so it is actually possible to do PCM playback, but there is no existing driver, so just using pwm-beeper for now, since it is also a compatible mode of operation.
