The charger thermistor on Lazor, CoachZ rev1 and Pompom rev1+2 is
either the wrong part or not stuffed at all, the same is true for
the skin temperature thermistor on CoachZ rev1. The corresponding
thermal zones are already disabled for these devices, in addition
delete the ADC nodes of the thermistors.
For Lazor and CoachZ rev1 also disable the PM6150 ADC thermal
monitor since there are no other temperatures to monitor.

Is there any other child node? I only see two, unless I missed
something. In which case the whole node can be disabled?

I see there's a 5v choke so this looks good as still enabled.

Right, the ADC itself can also be disabled in this case.

Yes, the ADC can be disabled here too.
