hwmon: (ina2xx) clean up unused define and outdated comment

The list of supported chips in the header is incomplete and contains no
other information not readily available. Remove the list and instead
hint that the chips supported by this driver have 219/226 compatible
register layout [unlike the ones supported by e.g. ina238].

Remove the unused INA226_DIE_ID define.
