If one thinks about real meaningful clk_prepare(), not like in EP93xx,
then clk_is_enabled_when_prepared() shall be considered and this might
change behaviour. That's why this "stupid" approach was chosen for this
conversion. Also, unfortunately, I don't have a test setup for PWM, this
made me shy towards this driver ;)
