hwmon: (ina238) add ina237 support
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.
