[34-longterm 053/260] USB: cdc-acm: Adding second ACM channel support for various Nokia and one Samsung phones

[Paul Gortmaker]

From: Toby Gray <toby.gray@xxxxxxxxxxx>

commit 4035e45632c2a8bb4edae83c20447051bd9a9604 upstream.

S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem
with a standard AT-command interface, which is picked up correctly by CDC-ACM.

The second ACM port is marked as having a vendor-specific protocol. This means
that the ACM driver will not claim the second channel by default.

This adds support for the second ACM channel for the following devices:
    Nokia E63
    Nokia E75
    Nokia 6760 Slide
    Nokia E52
    Nokia E55
    Nokia E72
    Nokia X6
    Nokia N97 Mini
    Nokia 5800 Xpressmusic
    Nokia E90
    Samsung GTi8510 (INNOV8)
