clk: pwm: Don't reconfigure running PWM at probe time

Browse source

If the PWM is enabled already when .probe() is entered, period and
duty_cycle are updated which essentially corresponds to a clock frequency
change. This is unusual and surprising. So update the settings only when
the clock gets prepared.
