Instead of reading a bunch of PWM debounce settings from the Devicetree,
set reasonable values inside the driver that are known to work across
multiple boards. There are no current users of these DT properties, so
no backward compatibility needs to be maintained. The properties can be
properly introduced in the binding in the future if different boards
really need to override them.
