USB: cdc-acm: Adding second ACM channel support for Nokia E7 and C7

commit 4061fde2fa80f40cb27114f60500d38d0afcf350 upstream.

This adds the Nokia E7 and C7 to the list of devices in cdc-acm, allowing
the secondary ACM channel on the device to be exposed. Without this patch
the ACM driver won't claim this secondary channel as it's marked as
having a vendor-specific protocol.
