   ## Summary
   Many PWM drivers can set channel output polarity (logical low or high) in 
idle state. This is usually set with a dedicated
   channel control register. This commit adds field `cpol` to `pwm_info_s` 
structure that allows the user to pass the information
   of desired polarity to architecture layer from application layer.
   
   Possibility of polarity change is added to samv7 driver.
   
   ## Impact
   None for current drivers as the functionality is not implemented there..
   
   ## Testing
   Tested on SAMv7 mcu.
