Implement charge current control depended on battery temperature #4

Closed jekhor closed 5 years ago

Battery should not be charged by high current when it too hot or too cold. Implement temp/current control table for charging. Accordingly with https://github.com/jekhor/yogabook-linux-android-kernel/blob/cm-13.0/drivers/power/bq2589x_charger.c#L1465 ,

Using of BQ25892 builtin thermal sensing and JEITA regulation should be sufficient if thermistor is connected properly (seems is).
