Fix breathing always on for soft PWM (#5983)

Browse source 
* Fix breathing always on for soft PWM

* Remove reference to hardware PWM pins in BACKLIGHT_BREATHING description

Now, breathing will only be unsupported when Timers 1 and 3 are both used by Audio

* Document BACKLIGHT_ON_STATE and its purpose
