This adds a property "mediatek,num-pwms" in example so that we could
set the number of PWM channels via device tree.

Wasn't there a comment in the last version to use num-pwms instead of
mediatek,num-pwms?

Uwe I think you requested that.

I think it is sensible, but it needs Thierry's blessing. Unfortunately
he seems busy with other stuff and getting feedback from him needs
patience.
