hwmon: (ina2xx) Add support for INA220 and INA230 



INA220 is register compatible to INA219, and INA230 is register compatible to
INA226, so all we need to do is to add name aliases for those two chips.

interface. The INA219 monitors both shunt drop and supply voltage, with

programmable conversion times and filtering.



The INA220 is a high or low side current shunt and power monitor with an I2C
