usb: misc: ljca: Drop _ADR support to get ljca children devices
Currently the shipped platforms use only _HID to distinguish
ljca children devices. The _ADR support here is for future HW.
This patch is to drop _ADR support and we can then re-introduce
it (revert this patch) if future HW actually starts using _ADR
to distinguish children devices.
