Fix the initialization and reference counting of the Gigaset driver modules
so that they can be unloaded when they are not actually in use.

Converts from using struct "class_device" to "struct device" making
everything show up properly in /sys/devices/ with symlinks from the
/sys/class directory.
Also fixes up the isdn drivers that were putting something in the class
device's directory.

Using the class device pointer returned by tty_register_device() with
part 1 of the patch, attach the Gigaset drivers' "cidmode" sysfs entry
to its tty class device, where it can be found more easily by users
who do not know nor care which USB port the device is attached to.

Fix a possible Oops in the Siemens Gigaset base driver when the device is
unplugged while an ISDN connection is still active, and makes sure that the
isdn4linux link level (LL) is properly informed if a connection is broken
by the USB cable being unplugged.
- Avoid unsafe checks of URB status fields outside the URB completion
handlers, keep track of in-use URBs myself instead.
- If an isochronous transfer URB completes with status==0, also check the
status of the frame descriptors.
- Verify length of interrupt messages received from the device.
- Align the length limit on transmitted AT commands with the device
documentation.
- In case of AT response receive overrun, keep newly arrived instead of old
unread data.
- Remove redundant check of device ID in the USB probe function.
- Correct and improve some comments and formatting.
