iio: Switch i2c drivers back to use .probe() After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

iio: chemical: sgp40: Convert to i2c's .probe_new() .probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function.

iio: chemical: Add driver support for sgp40 sgp40 is a gas sensor used for measuring the air quality. This driver is reading the raw resistance value which can be passed to an userspace algorithm for further calculation. The raw value is also used to calculate an estimated absolute voc index in the range from 0 to 500. For this purpose the raw_mean value of the resistance for which the index value is 250 might be set up as a calibration step. This can be done with in_resistance_calibbias. Compensation of relative humidity and temperature is supported and can be used by writing to output values of out_humidityrelative_raw and out_temp_raw. There is a predecesor sensor type (sgp30) already existing. This driver module was not extended because the new sensor is quite different in its i2c telegrams.
