drivers: Renamed ina220 --> ina2xx
The INA219 has the exact same interface as the INA220 (including values and semantics of the configuration register). Thus, this driver can be used for both. The ina220 has been renamed to ina2xx to reflect this and pseudo modules for the ina220 and ina219 have been added.
