pwm: stm32: Fix complementary output in round_waveform_tohw()
When the timer supports complementary output, the CCxNE bit must be set
additionally to the CCxE bit. So to not overwrite the latter use |=
instead of = to set the former.
Fixes: deaba9cff809 ("pwm: stm32: Implementation of the waveform callbacks")
