iio: potentiometer: ds1803: Convert enum->pointer for data in the ID table
Convert enum->pointer for data in the ID table, so that device_get_match_data() can do match against OF/ACPI/I2C tables, once i2c bus type match support added to it. Replace enum->struct *ds1803_cfg for data in the ID table and simplify ds1803_probe() by replacing device_get_match_data() with i2c_get_match_data().
