ng_ubt: Avoid attaching to several newer Intel controllers

Like other Intel controllers, these require firmware to be loaded, and
generic ng_ubt attach causes them to lock up until a power cycle.
However, their firmware interface for querying version info and loading
operational firmware is different from that implemented by ng_ubt_intel
and iwmbtfw, so they are not usable yet. Just disable attach for now to
avoid stalls during USB device enumeration.
