[PATCH 2/3] USB option driver K3765/K4505 avoid CDC_DATA interface

[Andrew Bird]

Currently the Option driver avoids binding interface 1 on Huawei K3765
and K4505 broadband modems as it should be handled by the cdc_ether
driver instead. This patch ensures we don't bind the interface 2
on those devices as that is CDC_DATA.
