Subject: [PATCH 3/4] arm64: dts: qcom: sc7180: pompom: Disable charger thermal zone for rev1 and rev2

Pompom rev1 and rev2 are 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.
