This patch series adds support for the third (optional) pwm cell to specify the
polarity.
Changes in V2:
* add ack and review tags

We need to increase the pwm-cells for the optional flags parameter,
before we can implement support for polarity setting via DT.

This adds support for the third (optional) pwm cell to specify the
polarity, which is needed by display backlights for example.
