iio: xilinx-xadc: 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.

In xadc_alloc_trigger, given dev is indio_dev->dev.parent, and we call
devm_iio_trigger_alloc wit dev as argument,  we do not have to set
data->trig->dev.parent to indio_dev->dev.parent anymore.
