"drd" means dual-role device, so usbhost cannot be labeled with the name contains "drd". Howerver, the label usbdrd_dwc3_0 was used for usbhost's dwc3 node. It seems it obviously fault because TM2 and TM2E doesn't use usbhost but dr_mode property is assigned to it. This patch assigns the proper label for two dwc3 nodes, and apply changes to the related reference.
