[Fix] Disable LPM on the Realtek USB Hub, and let xHCI controller make sure the link state transition is completed. [Test] After applying the patches, the Dell WD19 works reliably after thousand times for suspend/resume cycle. [Regression Potential] Low. This replaces the currently "msleep" way with more robust mechanism. I also test other systems and nothing breaks.
