arm64: dts: qcom: sc8180x: align thermal node name with bindings

Bindings expect thermal node names to end with 'thermal':

  sc8180x-lenovo-flex-5g.dtb: thermal-zones: 'gpu-thermal-bottom', 'gpu-thermal-top' do not match any of the regexes: '^[a-zA-Z][a-zA-Z0-9\\-]{1,12}-thermal$', 'pinctrl-[0-9]+'
