USB: Exposing second ACM channel as tty for Nokia S60 phones.

Browse Source 
Nokia S60 phones expose two ACM channels. The first is a modem and is picked
up by the standard AT-command interface information in the CDC-ACM driver. The
second is marked as having a vendor-specific protocol. Normally, we don't
expose those as ttys. (On some other devices, they may be claimed by the
rndis_host driver and used as a network interface).

But on S60 this second ACM channel is the way that third-party S60 application
developers are expected to communicate over USB. It acts as a serial device
at the S60 end, and so it should on Linux too.

The list of devices is largely derived from:
http://wiki.forum.nokia.com/index.php/S60_Platform_and_device_identification_codes
http://wiki.forum.nokia.com/index.php/Nokia_USB_Product_IDs
and includes only the S60 3rd Edition+ devices documented there.

There are many devices for which the USB device ID is not documented,
including:
    Nokia 6290
    Nokia E63
    Nokia 5630 XpressMusic
    Nokia 5730 XpressMusic

    Nokia 5530 XpressMusic (china)
    Nokia 5800 XM
    Nokia N97 (RM-506)
    Nokia N97 mini
    Nokia X6
It would be good to add those subsequently.
