From: Yuyang Du yuyang.du@intel.com
commit 1c9de5bf428612458427943b724bea51abde520a upstream.
This patch adds a USB3 HCD to an existing USB2 HCD and provides the support of SuperSpeed, in case the device can only be enumerated with SuperSpeed.
The bulk of the added code in usb3_bos_desc and hub_control to support SuperSpeed is borrowed from the commit 1cd8fd2887e162ad ("usb: gadget: dummy_hcd: add SuperSpeed support").
With this patch, each vhci will have VHCI_HC_PORTS HighSpeed ports and VHCI_HC_PORTS SuperSpeed ports.
