arm: tegra: usb: Exclude incompatible device from CDC-ACM driver.
A certain flashless modem has a boot ROM which incorrectly reports
itself as being USB CDC-ACM class compliant. Prevent the CDC-ACM
driver from printing error message about "This device cannot do
calls on its own. It is not a modem." when this device is present
on usb bus.
