USB option driver K3765/K4505 avoid CDC_DATA interface
commit 6118514e8749105334f46ccec6faf9a439be6cf9 upstream.
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.
