Don't use tiny step distances on the Z as that could cause a surprise
to users that copy the config without updating all the settings. (A Z
step distance that is too small would cause a high motor velocity.) A
step distance of .0025 is very popular in practice, so change the
default example configs to use that.

Specify hardware pwm cycle times using the same method as software pwm
(in seconds, not clock ticks). Allow the fan code to be configured
with an explicit cycle time even when using software pwm.
