arm64: dts: qcom: sc7180-aspire1: use generic ADC channel node names

ADC channel node names were changed to require generic 'channel'.  The
user-visible part is defined via label.

  sc7180-acer-aspire1.dtb: adc@3100: 'charger-thermistor@4f', 'thermistor@4e' do not match any of the regexes: '^channel@[0-9a-f]+$', 'pinctrl-[0-9]+'
