    USB: introduce usb_interface/usb_configuration structs

    Currently we have two conflicting definitions of struct
usb_config_descriptor
    and struct usb_interface_descriptor in the tree. This is because the
USB code
    uses additional fields in the structs for internal housekeeping. Add
    struct usb_interface and struct struct usb_configuration with the
housekeeping
    data and embed the corresponding hardware structs into them. This
frees the
    way to use the definitions from ch9.h in the next step.
