iio:trigger: Introduce iio_tigger_{set,get}_drvdata
Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific
data to a trigger. The functions wrap access to the triggers private_data field
and all current users are updated to use iio_tigger_{set,get}_drvdata instead of
directly accessing the private_data field. This is the first step towards
removing the private_data field from the iio_trigger struct.
The following coccinelle script has been used to update the drivers:
<smpl>

struct iio_trigger *trigger;

+iio_trigger_set_drv_data(trigger, priv)
