    usb: split usb_new_device for clarity and refactoring · d9d16e8a

    This patch takes hub.c:usb_new_device() and splits it in three parts:
    
    - The actual actions of adding a new device (quirk detection,
      announcement and autoresume tracking)
    
    - Actual discovery and probing of the configuration and interfaces
      (split into __usb_configure_device())
    
    - Configuration of the On-the-go parameters (split into
      __usb_configure_device_otg()).
    
    The fundamental reasons for doing this split are clarity (smaller
    functions are easier to maintain) and to allow part of the code to be
    reused when authorizing devices to connect.
    
    When a device is authorized connection, we need to run through the
    hoops we didn't run when it was connected but not authorized, which is
    basically parsing the configurations and probing
    them. usb_configure_device() will do that for us.
