arm64: dts: qcom: sc7280: Move dp_hot_plug_det pull from SoC dtsi file

Pulls should be in the board files, not in the SoC dtsi
file. Remove. Even though the sc7280 boards don't currently refer to
dp_hot_plug_det, let's re-add the pulls there just to keep this as a
no-op change. If boards don't need this / don't want it later then we
can remove it from them.
