Commit Message

Lazor is stuffed with a 47k NTC as thermistor for the charger
temperature which currently isn't supported by the PM6150 ADC
driver. Disable the charger thermal zone to avoid the use of
bogus temperature values.

Changes in v2:
- disable the thermal zone instead of deleting the zone and ADC nodes
- updated subject and commit message

> Subject: [PATCH v2 2/4] arm64: dts: qcom: sc7180: Disable charger thermal for lazor

Should be 'Disable charger thermal *zone* for lazor'

Maybe Bjorn can fix this when applying if no respin is needed.
