Subject: [PATCH 06/19] usb: dwc3: host: Pass the XHCI_DRD_SUPPORT and XHCI_NEEDS_LHC_RESET quirk

Pass the quir flag XHCI_DRD_SUPPORT from DWC3 host to xhci platform driver.
This enables xhci driver to handle deallocation's differently while in DRD mode.
Pass the quirk flag XHCI_NEEDS_LHC_RESET from DWC3 host to xhci platform
driver. This enables to do LHRESET during xhci_reset().
