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
+ * @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
  *
- * FIXME: Write the kerneldoc!
+ * 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
