There's one other PWM with 'open-drain' so move the definition to 
pwm.yaml.

Alternatively, 'drive-open-drain' is a much more commonly used 
variation.

Another thing to consider is for any PWM controller with more than 
1 output, you might want this to be per output and therefore should be 
a flag in the cells.
