pwm: rockchip: Allow polarity invert on rk3288
The rk3288 has the ability to invert the polarity of the PWM. Let's enable that ability. Note that this increases pwm_cells to 3 for rk3288. Signed-off-by: Doug Anderson <email@example.com> Reviewed-by: Caesar Wang <firstname.lastname@example.org> Signed-off-by: Thierry Reding <email@example.com>
