s-holst c20a830e63 config: Fix M300 beeper example. (#4480) ...

The M300 example macro now sets the PWM cycle time to generate the requested
frequency. 'scale' did not have the desired effect. Duty cycle is now
fixed at 0.5. All S parameter values less than 1 generate a 1Hz 'tone'
to avoid division-by-zero.
