arm64: dts: qcom: sc8280xp-crd: use external pull up for touch reset
The touch controller reset line is currently not described by the devicetree except in the pin configuration which is used to deassert reset. As the reset line has an external pull up to an always-on rail there is no need to drive the pin high so just leave it configured as an input and disable the internal pull down.
