iio: chemical: vz89x: Convert enum->pointer for data in the match tables
Convert enum->pointer for data in the match tables, 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 *vz89x_chip_data for data in the match table. Simplify
the probe() by replacing device_get_match_data() and ID lookup for
retrieving data by i2c_get_match_data().
