USB: cdc-acm: add usb id for motomagx phones

commit 155df65ae11dfc322214c6f887185929c809df1b upstream.

The Motorola MOTOMAGX phones (Z6, E8, Zn5 so far) are providing
combined ACM/BLAN USB configuration. Since it has Vendor Specific
class, the corresponding drivers (cdc-acm, zaurus) can't find it just
by interface info. This patch adds usb id so the cdc-acm driver can
properly handle this combined device.
