arm64: dts: qcom: sm6125: Append -state suffix to pinctrl nodes

According to qcom,sm6125-pinctrl.yaml all nodes inside the tlmm must be
suffixed by -state:

    qcom/sm6125-sony-xperia-seine-pdx201.dtb: pinctrl@500000: 'sdc2-off', 'sdc2-on' do not match any of the regexes: '-state$', 'pinctrl-[0-9]+'

The label names have been updated to match, going from sdc2_state_X to
sdc2_X_state.
