The exc3000_id.driver_data could store a pointer to the info,
like for ACPI/DT-based matching, making I2C, ACPI 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, ACPI and DT-based matching table.
