pwm_cycle_time: New module for output pins with dynamic cycle times

Browse source 
Remove support for changing the cycle time of pwm pins from the
output_pin module.  Use a new pwm_cycle_time module that supports
setting dynamic cycle times.  This simplifies the output_pin code and
low-level pin update code.
