USB: xhci: Allocate and address USB devices
xHCI needs to get a "Slot ID" from the host controller and allocate other data structures for every USB device. Make usb_alloc_dev() and usb_release_dev() allocate and free these device structures. After setting up the xHC device structures, usb_alloc_dev() must wait for the hardware to respond to an Enable Slot command. usb_alloc_dev() fires off a Disable Slot command and does not wait for it to complete. When the USB core wants to choose an address for the device, the xHCI driver must issue a Set Address command and wait for an event for that command.
