PWM calculation correction.

Browse Source 
- The PWM calculation was a little bit off and has been corrected.

- Edited the unused settings strings to be smaller and just show what
the settings are, rather than include units. May include this in the
master build, if it fits.

- The minimum spindle PWM define in config.h needed to be update for
cpu map compatibilty.

// in mind that you will begin to lose PWM resolution with increased minimum PWM values, since you have less

// By default on a 328p(Uno), Grbl combines the variable spindle PWM and the enable into one pin to help
