Drop unused labels. Everywhere. You are not making the code more readable.

Why do you reference internal design of the device as DTS? You cannot
have here other power supply, can you?

I will remove them.

I mistakenly thought power_supply_am_i_supplied() required power-supplies
property, it actually does not, I will remove it.
