iio:trigger: Use dev_{set,get}_drvdata for private data management

Use dev_{set,get}_drvdata for managing private data attached to a trigger
instead of using a custom field in the iio_trigger struct.

 allocates a trigger structure.  The key elements to then fill in within
 a driver are:
 
-trig->private_data
-	Device specific private data.
-
 trig->owner
 	Typically set to THIS_MODULE. Used to ensure correct
