iio: adc: ad7192: Fix null ad7192_state pointer access
Pointer to indio_dev structure is obtained via spi_get_drvdata() at
the beginning of function ad7192_setup(), but the spi->dev->driver_data
member is not initialized, hence a NULL pointer is returned.
Fix by changing ad7192_setup() signature to take pointer to struct
iio_dev, and get ad7192_state pointer via st = iio_priv(indio_dev);
Fixes: bd5dcdeb3fd0 ("iio: adc: ad7192: convert to device-managed functions")
