The ltc4306_id[].driver_data could store a pointer to the chips,
like for DT-based matching, making I2C and DT-based matching
more similar.
After that, we can simplify the probe() by replacing of_device_get_
match_data() and i2c_match_id() by i2c_get_match_data() as we have
similar I2C and DT-based matching table.
