[PATCH] ARM: dts: sun8i-v3s: Add PWM controller and pins definitions

[Paul Kocialkowski]

This introduces definitions for the PWM controller found in the V3s,
as well as associated pins. This fashion of the controller has two PWM
outputs and is register-compatible with the A20.

Both PWM outputs were tested on a Lichee Pi Zero with a simple
transistor-LED setup.
