These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Class-based I2C probing requires detect() and address_list to be
set in the I2C client driver, see checks in i2c_detect().
It's misleading to declare I2C_CLASS_HWMON support if this
precondition isn't met.

The INA237 "85-V, 16-Bit, Precision Power Monitor With I2C Interface" is
basically the same as INA328. Therefore add a corresponding compatible
to the driver.
According to the datasheet the main difference is the current and power
monitoring accuracy:
+------------------------+---------------+---------------+
| | INA238 | INA237 |
+------------------------+---------------+---------------+
| Offset voltage | +/- 5µV | +/- 50µV |
| Offset drift | +/- 0.02µV/°C | +/- 0.02µV/°C |
| Gain error | +/- 0.1% | +/- 0.3% |
| Gain error drift | +/- 25ppm/°C | +/- 50ppm/°C |
| Common mode rejection | 140dB | 120dB |
| Power accuracy | 0.7% | 1.6% |
+------------------------+---------------+---------------+
As well as the missing DEVICE_ID register at 0x3F, which is currently
not in use by the driver.

After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("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.

The INA238 is a I2C power monitor similar to other INA2xx devices,
providing shunt voltage, bus voltage, current, power and temperature
measurements.
