iio: adis_trigger: Remove code to set trigger parent

iio_trigger_set_drvdata() sets the trigger device parent to first
argument of viio_trigger_alloc(), no need to do it again in the driver
code.
Remove adis_trigger_setup() to match other drivers where setting the
trigger is usually done in the probe() routine.
