This reverts commit e17af1c9d861dc177e5b56009bd4f71ace688d97. Removing the delay of 100 units broke hot plug detection for USB-C displays on qcom sc7180 lazor devices. Lazor uses mdss for hot plug detection and declares dp_hot_plug_det in the dts. Other sc7180 based devices like aspire1 were not affected by the regression, as they do not rely on mdss and dp_hot_plug_det for hot plug detection.
