arm64: dts: qcom: msm8916-thwc-ufi001c: add function to pin config

Bindings require pin configuration nodes to have the function, even if
it is GPIO:

  msm8916-thwc-ufi001c.dtb: pinctrl@1000000: sim-ctrl-default-state: 'oneOf' conditional failed, one must be fixed:
    'esim-sel-pins', 'sim-en-pins', 'sim-sel-pins' do not match any of the regexes: 'pinctrl-[0-9]+'
