USB: convert usb.h struct usb_device to kernel-doc

Convert struct usb_device to use kernel-doc notation.
Please especially check the @filelist and @usb_classdev descriptions.

* struct usb_device - kernel's representation of a USB device
*
* FIXME: Write the kerneldoc!
*
* @devnum: device number; address on a USB bus
* @devpath: device ID string for use in messages (e.g., /port/...)
* @state: device state: configured, not attached, etc.
* @speed: device speed: high/full/low (or error)
* @tt: Transaction Translator info; used with low/full speed dev, highspeed hub
* @ttport: device port on that tt hub
* @toggle: one bit for each endpoint, with ([0] = IN, [1] = OUT) endpoints
* @parent: our hub, unless we're the root
* @bus: bus we're part of
* @ep0: endpoint 0 data (default control pipe)
* @dev: generic device interface
* @descriptor: USB device descriptor
* @config: all of the device's configs
* @actconfig: the active configuration
* @ep_in: array of IN endpoints
* @ep_out: array of OUT endpoints
* @rawdescriptors: raw descriptors for each config
* @bus_mA: Current available from the bus
* @portnum: parent port number (origin 1)
* @level: number of USB hub ancestors
* @can_submit: URBs may be submitted
* @discon_suspended: disconnected while suspended
* @persist_enabled: USB_PERSIST enabled for this device
* @have_langid: whether string_langid is valid
* @authorized: policy has said we can use it;
* (user space) policy determines if we authorize this device to be
* used or not. By default, wired USB devices are authorized.
* WUSB devices are not, until we authorize them from user space.
* FIXME -- complete doc
* @wusb: device is Wireless USB
* @string_langid: language ID for strings
* @product: iProduct string, if present (static)
* @manufacturer: iManufacturer string, if present (static)
* @serial: iSerialNumber string, if present (static)
* @filelist: usbfs files that are open to this device
* @usb_classdev: USB class device that was created for usbfs device
* access from userspace
* @usbfs_dentry: usbfs dentry entry for the device
* @maxchild: number of ports if hub
* @children: child devices - USB devices that are attached to this hub
* @pm_usage_cnt: usage counter for autosuspend
* @quirks: quirks of the whole device
* @urbnum: number of URBs submitted for the whole device
* @active_duration: total time device is not suspended
* @autosuspend: for delayed autosuspends
* @pm_mutex: protects PM operations
* @last_busy: time of last use
* @autosuspend_delay: in jiffies
* @connect_time: time device was first connected
* @auto_pm: autosuspend/resume in progress
* @do_remote_wakeup: remote wakeup should be enabled
* @reset_resume: needs reset instead of resume
* @autosuspend_disabled: autosuspend disabled by the user
* @autoresume_disabled: autoresume disabled by the user
* @skip_sys_resume: skip the next system resume
*
* Notes:
* Usbcore drivers should not set usbdev->state directly. Instead use
* usb_set_device_state().
*
* @authorized: (user space) policy determines if we authorize this
* device to be used or not. By default, wired USB
* devices are authorized. WUSB devices are not, until we
* authorize them from user space. FIXME -- complete doc
