add setting to adjust charging current limit

[SinKy-Yan]

Description of the feature you're suggesting.

I'm using a DIY Flipper Zero, and its PMU inductor packaging is incorrect. It overheats at the default charging current. I'd like to add a setting to adjust the charging current in the power settings. I noticed the driver already records the corresponding register locations. I tried using ChatGPT to write code for adding this setting, but it didn't succeed.

Anything else?
