[U-Boot] [PATCH 09/16] usb: xhci: Change xhci_setup_addressable_virt_dev() signature

[Bin Meng]

For future extension, change xhci_setup_addressable_virt_dev()
signature to accept a pointer to 'struct usb_device', instead
of its members slot_id & speed, as the struct already contains
these two plus some other useful information of the device.
