pwm: kona: Modify settings application sequence
Update the driver so that settings are applied in accordance with the most recent version of the hardware spec. The revised sequence clears the trigger bit, waits 400ns, writes settings, sets the trigger bit, and waits another 400ns. This corrects an issue where occasionally a requested change was not properly reflected in the PWM output.
